Scope of application

DZ30-32 Miniature Circuit Breakers(DPN MCB) are designed for single-phase residential circuits of AC 50Hz or 60Hz, rated voltages of 230V, and protects against overload and short-circuiting of electrical circuits. Zero and Fire line be cut off in the same time to eliminate the fire line and zero line connected to reverse or failure and fire hazard from zero line to ground potential, the 240V Circuit Breakeris the ideal distribution protection switch in the field of residential housing. This product complies with standards of IEC60898-1 and GB10963.1. DZ30-32 32 amp Circuit Breakeris produced by TAIXI have got national CCC certification.

DZ30 32 Amp Circuit Breakers have high breaking capacity, small size and compact structure. The 240V Circuit Breakers have two poles (P + N) within width of Two Poles One Module (18mm). Phase line and N line be cut off at the same time, and the N pole has the advantage of being turned on first and then disconnected, which avoid phase line, N line reverse or personal risk from N line to ground voltage.
Use wire connection, the max round copper wire accessed is 10nm ² .
Use TH35-7.5 standard steel mounting rail for installation.

Structural features

DZ30 240V Circuit Breakers have small size, compact structure, 1P + N two-poles within 18MM width, and have half width of DZ47 two poles product, the price is better than similar products.
Casing and some functional part of DZ30 circuit breaker are made of plastic with high flame retardant, high temperature, impact resistant.
DZ30 240V Circuit Breaker directly with the zero line installation, to avoid the potential error of the zero line wiring potential shock hazard.
The DZ30 32 amp Circuit Breaker is installed by rail, which is convenient and time-saving.
