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 230V Circuit Breaker is 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 DIHOOL have got national CCC certification.
MAIN TECHNICAL PARAMETERS
■ Rated Current: 6, 10, 16, 20, 25, 32 A
■ Impulse Withstand Voltage: 4kV
■ Mechanical Life: 10000 times
■ Electrical Life: 4000 times
■ Use Ambient Temperature: ambient temperature -5°C+40°C the average temperature within 24h does not exceed 35°C
■ Altitude: ≤2000m.
■ Standard: IEC60898-1/GB10963.1
■ Compliance Certification: CE, CCC
■ Tripping Characteristics: protection of conventional loads and distribution cables, instantaneous tripping range (5~10) In
■ Installation Method: use TH35-7.5 mounting rail to install. The product is directly installed with the neutral wire to avoid the potential danger of electric shock due to the wrong wiring of the neutral wire.

STRUCTURE
DZ30 DPN Circuit Breakers have high breaking capacity, small size and compact structure. Within the width of two poles and one module (18mm), there are two poles (L+N), the phase line and N line are cut at the same time, and the N pole is first The advantage of disconnecting after being turned on prevents the personal danger caused by the reverse connection of the phase line, the N line or the voltage of the N line to the ground.
The wire connection method is adopted, and the maximum round copper wire of 10mm² can be connected.
Use TH35-7.5 standard steel mounting rail for installation.
DZ30 circuit breaker is small in size and compact in structure. It has 1P+N poles within 18MM width, which is half the width of DZ47 two-pole products, and the price ratio is better than similar products.
DZ30 circuit breaker shell and some functional parts are made of high flame retardant, high temperature resistant and impact resistant plastic.
DZ30 circuit breakeris installed directly with the neutral line to avoid the potential danger of electric shock due to the wrong wiring of the neutral line.
Dz30 miniature circuit breakers are installed on rails, which is convenient and time-saving.
