HZMB series plastic shell circuit breakerDetailed product description：

The HZMB series plastic shell circuit breaker (hereinafter referred to as the circuit breaker) is one of the new types of circuit breakers developed by our company using international advanced technology and manufacturing technology. Its rated insulation voltage is 800V (HZMB-63 is 500V), suitable for circuits with AC 50Hz, rated working voltage of 690V and below (HZMB-63 is 400V), and rated working current up to 800A for infrequent switching and motor starting. Circuit breakers have overload, short circuit, and undervoltage protection functions, which can protect the circuit and power equipment from damage.
Circuit breakers are classified into three types based on their rated ultimate short-circuit breaking capacity (LCU) for high voltage: L-type (standard type), M-type (higher breaking type), and H-type (high breaking type)

It has the characteristics of small size, high breaking height, short arc (some specifications have zero arc), and anti vibration, making it an ideal product for land and ship use.
The HZMB series plastic shell circuit breaker can be installed vertically or horizontally
The HZMB series plastic shell circuit breaker cannot be reversed, that is, only 1, 3, and 5 can be connected to the power line, and 2, 4, and 6 can be connected to the load line
The HZMB series plastic shell circuit breaker products comply with the following standards
IEC 60947-1 and GB/T 14048.1 General principles
IEC 60947-2 and GB 14048.2 Low Voltage Circuit Breakers
