JZM1 Series
Moulded Case Circuit Breaker

Introduction

JZM1 Series Moulded Case Circuit Breakers (MCCB) are suitable for circuits with rated working voltage of 400VAC(50Hz), and rated working current of 800A. JZM1 series circuit breakers have the advantages of high breaking capacity, short arcing (zero arcing for some specifications), anti-vibration, reasonable design, safety and reliability, small size, light weight, and beautiful appearance. They are ideal products for land and ship use. JZM1 series circuit breakers have overload, short circuit and undervoltage protection functions, which can protect the circuit and power equipment from damage. According to its rated ultimate short-circuit breaking capacity (Icu), JZM1 series circuit breakers can be divided into three types: L type (standard capacity type), M type (middle breaking capacity type), and H type (high breaking capacity type). JZM1 series circuit breakers can be equipped with a variety of accessories, which have the advantages of quick installation, convenient use and strong applicability. JZM1 series circuit breakers can be installed vertically or horizontally. The wiring of  JZM1 series circuit breaker cannot be reversed, that is, Port 1, 3, and 5 can be only  connected to the power supplier, and Port 2, 4, and 6 can be only connected to the load.
