China DZ47LED-63 Residual Current Circuit Breaker Manufacturers, Suppliers, Factory

High voltage vacuum circuit breakers (VCB) are safety switches that turns power off to provide safety during lightning strikes and through the neutral sections on the overhead lines. TE's vacuum circuit breaker for rolling stock was the first completely electro-magnetically operated system for 25kV and 15kV vehicles.

Leakage Protection Socket, also known as 86-type leakage protection socket. It is the one of the patented products researched and developed independently by our company using international advanced design and advanced manufacturing technology.

DW45 Air Circuit Breaker is suitable for the circuit of AC 50Hz/60Hz with rated service voltage 400V, 690V and rated service current up to 6300A.It is mainly used to distribute electric energy and protect circuits and electric equipment against over-load, under-voltage, short-circuit and single-phase earthing fault.

The primary wiring diagram to see the picture. The control power is derived from normal power，emergency power cand N phases. Ⅰ and Ⅱ line control power AC220V connected with terminal 102~103,104~105respectively,102 and 104 are normal power and emergency power live line respective. Terminal 101,106 are acting as a signal lamp to control the power supply. Note:101 and 106 couldn’t be connected with any other lines. When above(under) input line, under(above)terminal Ⅰ and Ⅱ line A, B, C phases will be connected with copper lines or lines acting as output.

The automatic recovery over voltage and under voltage protective device complies with modular design standards. the circuit boards of products adopt good quality electronic components with reliable pe.

DBW SBW Power Voltage Stabilizer is a contact adjustable automatic voltage compen-sation high-power regulating power device. When voltage from supply network is varied or dueto loading current effect, it automatically regulates the output voltage to ensure the normal func-tion of the varied of electric equipments.
