In today's rapidly developing electrical industry, safety and reliability remain the top priorities for both residential and commercial electrical systems. Among the many circuit protection devices available, the DZ30 DPN MCB (Miniature Circuit Breaker) stands out for its precision engineering, compact design, and dependable performance. As someone deeply involved in electrical system maintenance, I often ask myself: Why do so many professionals recommend the DZ30 DPN MCB? The answer lies in its superior build quality, advanced safety mechanisms, and easy installation features that make it a preferred choice across various applications.
The DZ30 DPN MCB is a single-pole plus neutral (1P+N) miniature circuit breaker designed to protect electrical circuits from overload and short-circuit conditions. It combines both live and neutral isolation in a single compact device, ensuring enhanced protection and convenient wiring. This model is particularly suited for low-voltage power distribution in homes, offices, and industrial systems.
Unlike traditional circuit breakers, the DZ30 DPN MCB integrates thermal-magnetic trip technology, which ensures fast response and long service life. Its high-quality materials and precise mechanism guarantee stable operation even in fluctuating power environments.
Below is a detailed specification table outlining the key technical features of the DZ30 DPN MCB:
| Parameter | Specification |
|---|---|
| Model | DZ30 DPN MCB |
| Rated Current (In) | 6A, 10A, 16A, 20A, 25A, 32A |
| Rated Voltage (Ue) | 230V AC |
| Rated Frequency | 50/60Hz |
| Number of Poles | 1P+N (Single Pole + Neutral) |
| Breaking Capacity | 6kA |
| Tripping Curve | Type C or B |
| Rated Insulation Voltage | 500V |
| Electrical Life | ≥ 4000 operations |
| Mechanical Life | ≥ 10,000 operations |
| Mounting Method | 35mm DIN rail |
| Connection Type | Screw terminal |
| Ambient Temperature | -5°C to +40°C |
| Standard Compliance | IEC/EN 60898-1 |
This technical configuration shows that the DZ30 DPN MCB is not only versatile but also built to meet international safety and performance standards.
The DZ30 DPN MCB significantly enhances electrical safety through its dual protection mechanism — thermal for overload and magnetic for short-circuit protection. When the current exceeds its rated limit, the breaker automatically trips, cutting off power instantly to prevent damage to electrical appliances and wiring systems.
Moreover, the integrated neutral disconnection feature ensures that both live and neutral lines are isolated simultaneously during faults. This prevents potential electric shock hazards and ensures complete isolation during maintenance work.
ZHEJIANG SINGI ELECTRICAL LLC designs and manufactures the DZ30 DPN MCB using high-quality flame-retardant materials, ensuring resistance to heat and fire, further reinforcing its safety profile.

Stable Tripping Performance: Accurate response to overload and short-circuit conditions.
High Durability: Long mechanical life ensures consistent operation over years.
Compliance with Global Standards: Fully conforms to IEC/EN 60898-1, ensuring international reliability.
The versatility of the DZ30 DPN MCB makes it suitable for a variety of applications:
Residential Buildings: Protects lighting and socket circuits.
Commercial Facilities: Ensures safety in office electrical distribution systems.
Industrial Settings: Provides reliable protection for small machinery and control systems.
Renewable Energy Systems: Can be applied in low-voltage solar distribution boxes.
Q1: What does "DPN" mean in DZ30 DPN MCB?
A1: "DPN" stands for "Double Pole Neutral," which means the breaker disconnects both the live (phase) and neutral wires simultaneously, ensuring full circuit isolation for improved safety.
Q2: How does the DZ30 DPN MCB differ from a standard MCB?
A2: Unlike standard MCBs that only disconnect the live wire, the DZ30 DPN MCB isolates both live and neutral poles, making it safer and more suitable for single-phase residential and commercial applications.
Q3: Can the DZ30 DPN MCB be used for high-power devices?
A3: The breaker is suitable for devices within its rated current range (up to 32A). For high-power industrial machines, larger circuit breakers with higher ratings should be used.
Q4: How do I choose the right current rating for my DZ30 DPN MCB?
A4: The current rating depends on the load of your circuit. For example, 10A or 16A is typically used for lighting, while 20A or 32A may be used for sockets or air-conditioning circuits. Consulting a qualified electrician ensures correct selection.
