CJ CPS Control Protective Switch

CPS (Control Protective Switch)(CPS)) is a low-voltage electrical appliances in the new product, is the latest research and development in the 1990s to fill the gaps in the first generation of domestic products, its product category code-named "CPS", is the English "Control and Protective switching device", which conforms to IEC 60947-6-2 (1997)" Low-voltage switchgear and controlgear Part 6: Multifunctional electrical appliances Section 2: Control and protection switchgear "(August 1992 Version 1) and GB14048.9-1998 "Low-voltage switchgear and control multifunctional electrical appliances (equipment) Part 2: Control and protection switchgear (equipment)" (equivalent to IEC60947-6-2). IEC standards and national standards for the code and electrical code as shown.

CJ CPS Control Protective Switch's main features is achieving control and protection function of integration and internal coordination in the product of single structure. It can replace the circuit breaker (fuse), contact overload (or over-current, open- ) protection relays, starter isolators, motor integrated protector and other traditional separation components. CPS can control the operate by both ways of remote automatic control and local manual control, with the time-current protection features of coordination and cooperation, with control and protection's continuous operation after the short circuit. It has the advantages of high breaking capacity, small arcing distance, long life, adjustable protection setting current, easy operation, complete supporting accessory module and so on. It can control and protect the motor load and distribution load.

CJ CPS Control Protective Switch can basically solve various traditional problems that unreasonable coordination of the control and protection is caused by the unreasonable choice of discrete components (usually circuit breakers or fuses + contactors + overload relay).Especially to overcome the discordant coordination of protection characteristics and control characteristics due to using combination with different assessment standards of electrical products , greatly improves the operational reliability and continuous operation performance of the control and protection system.

CJ CPS Control Protective Switches are based on the latest microelectronics technology, based on peer products, is KCPS series digital control and protective switching electrical products developed with the characteristics of the our company, to overcome the shortcomings of peer products, brings together the advantages of the low-voltage electrical components, complete function, reliable performance, provides basic components for the simplification and optimization of low-voltage distribution and control system.

The main parameters

Two mounting dimensions: Type 125 (D-frame) and Type 45 (C-frame).

The number of poles of the main circuit is divided into three poles and four poles.

CJCPS control and protection of the basic configuration of switchgear: the main + intelligent controller + auxiliary contact group.

The main body of the main circuit by the basic module that is "contact system module, short-circuit release, electromagnetic system modules and operating system modules.

Short-circuit breaking capacity rating: Economy (C) 35kA, standard type (Ah) 50kA, high breaking type (H) 80kA.

It is expected that the breaking time under short circuit current is 2 ~ ms and the current limiting coefficient is 0.2 or less.

_Auxiliary contact group consists of short-circuit alarm contact, overload alarm contact and a group of 2 normally open 1 normally closed auxiliary contact composition, 02 is 2 normally open 1 normally closed +1 short circuit 1 overload, 06 is 3 normally open 3 often Close to 1 short circuit 1 overload.

Can be combined according to user requirements, but up to no more than 11 pairs of contacts.

Intelligent controller rated current le: 0.4 / 1 / 2.5 / 4 / 6.3 / 12/16/18/25/32/40/45/50/63/80/100 / 125A.

• Body rated current 丨 n: 12/16/18/32/45/63/100 / 125A.

Number of poles: two digits (the first digit indicates the number of poles and the last digit indicates the number of poles).

Very protective, 30 means 3-pole without protection.

• Control power supply voltage: M: AC220V, 〇: AC380V

Function and use

CJCPS Control Protective Switch uses a modular single product structure type, integrated traditional circuit breakers (fuses), contactors, overload (or overcurrent, phase failure) protection relays, starters, starters, isolators, motor integrated protector, etc. Low-voltage electrical products, the main function, with long-range automatic control and local direct human control function, with panel instructions and mechanical and electrical signal alarm function, with overvoltage undervoltage protection, with phase failure phase protection, Function, with the time to adjust the current - current protection characteristics (with overload inverse time, definite time, short circuit instantaneous, large short circuit instantaneous four protection characteristics). According to the need to match the functional modules or accessories, you can achieve all kinds of motor load, power distribution control and protection.

CJCPS Control Protective Switch is mainly used for AC 50Hz (60Hz), rated voltage to 690V, the main rated current from 6.3 to 125A, intelligent controller adjustable operating current from 0.16A to 125A, control motor power from 0.05KW to 5 5KW power system To carry and break current under normal conditions (including specified overload conditions) and to be able to turn on, carry and break current under specified non-normal conditions (eg short circuit).

Applicable areas

CJ CPS Control Protective Switch with integrated control and protection functions, modular structure, miniaturization, high degree of protection of environmental pollution, breaking short-circuit current capacity, short arc distance, long life, complete protection, continuous operation performance and reliability High installation and easy maintenance and a series of advantages, in industrial facilities, infrastructure, fire systems and commercial and civilian facilities are widely used;

Lu metallurgical, coal mine, steel, petrochemical, port, ship, railway and other areas of the distribution and motor protection and control system;

Motor control center (MMC) and distribution center;

Highway lighting, ventilation system

Military station control system (such as border posts, radar stations, etc.);

Fire pumps, fans, etc. of various occasions;

Modern building lighting, power conversion, pumps, fans, air conditioning, fire, lighting, etc .;

Remote control lighting system;

Time current characteristics

Main feature

According to the protection object is divided into: the motor protection, power distribution protection according to the operating frequency is divided into: frequent operation, not frequent operation by wiring is divided into: board, board, insert according to the working principle is divided into: digital tube controller, Type controller

Separate electrical appliances compared to the system (see table below)

With the control and protection from the characteristics of self

CJCPS Control Protective Switch series control and protection switchgear set control and protection functions in one, the equivalent of circuit breaker (fuse) + contact + thermal relay + auxiliary electrical appliances. Which can solve the problem of the protection and control characteristic matching between the components which can not be or can be solved by the separation element, so that the protection and control characteristics can be better and reasonable (with inverse time, definite time and instantaneous three protection characteristics) Load power or current can choose a single product, instead of the previous, including from the power into the load to the end of a variety of electrical appliances, do not need to derail; greatly reduce the workload of the designer.

With unparalleled operational reliability and continuous operating performance of the system

CJCPS Control Protective Switch in the breaking short-circuit current without maintenance can be put into use, that is, with a short circuit after breaking the continuous operation performance: CJCPS after breaking short-circuit current test, still have more than 6000 times AC-44 electrical life, which is broken And other discrete devices constitute the system is difficult to achieve, CJCPS this feature greatly improves the system's remote reliability and continuous operation of the system performance, which run short-circuit breaking capacity Ics 80kA indicators are similar products of the international leader , The highest domestic indicators.

Saving energy

CJCPS Control Protective Switch has a small size, the installation area and the volume is small, no separation of component contacts, reduce the line heat, save energy, save materials and so on.
