1、 Scope of application

DZ30-32 (DPN) miniature circuit breaker "phase line+neutral line" is suitable for single-phase residential lines with a rated voltage of 230V at 50Hz or 60Hz, to protect against overload and short circuit of electrical circuits. This product has high breaking capacity, small size, and a width of 18mm. It cuts off both the neutral and live lines simultaneously, eliminating the personal and fire hazards caused by the reverse connection of the live and neutral lines or the neutral line to the ground. It is currently the most ideal distribution protection switch in the field of civil residential buildings. This product complies with the requirements of standards such as IEC60898 and GB10963.1.

2、 Model and specifications

3、 Structural features

DZ30seriesDPN circuit breakerHigh breaking capacity, small size, compact structural dimensions, with two poles (P+N) within one module width (18mm) of two poles. The phase line and N line are simultaneously cut off, and the N line has the advantage of being connected first and then disconnected, eliminating personal danger caused by reverse connection of phase line and N line or N line to ground voltage.
Using wire connection method, it can connect up to 10nm ² round copper wire.
Install the guide rail using TH35-7.5 standard steel.

4、 Structural characteristics

The DZ30 circuit breaker has a small volume and compact structure, with 1P+N poles within a width of 18mm, which is half the width of the DZ47 two pole product. The price is better than similar products.
DZ30The circuit breaker housing and some functional components are made of high flame retardant, high temperature resistant, and impact resistant plastic.
DZ30 products are directly installed with a neutral wire to avoid potential electric shock hazards caused by incorrect neutral wire wiring.
DZ30 miniature circuit breakerAdopting guide rail installation, convenient and time-saving.

6、 Appearance and installation dimensions

7、 The difference between 1P miniature circuit breaker and DZ30 circuit breaker:

A 1P miniature circuit breaker means that the live wire enters the circuit breaker and the neutral wire does not enter. DPN means that both the live and neutral wires enter the circuit breaker, which can simultaneously cut off the live and neutral wires. For users, it is safer and easier to inspect.
2P miniature circuit breakers are also double in and double out, meaning that both the live and neutral wires enter the circuit breaker, but the width of 2P circuit breakers is twice that of 1P and DPN circuit breakers.
