Modular Case Residual Current Circuit Breaker
JZM1LE Series Modular Case Residual Current Circuit Breaker (MRCB, also know as Modular Case Residual Current Device, MRCD) is suitable for circuits with a rated voltage of 400VAC (50Hz) and a rated current of 16A to 800A, in line with GB14048.2 and IEC60947-2 standards. JZM1LE series circuit breakers are mainly used to provide indirect contact protection for people who are at risk of electric shock, or to prevent electrical fires caused by contact with fault currents. It can also be used to protect circuits from overload and short-circuit. When other protection measures fail, JZM1LE series residual current circuit breaker with a rated residual operating current not exceeding 0.03A can be used as a supplementary protection for direct contact, but it cannot be used as the only direct contact protection. JZM1LE series circuit breakers have the advantages of small size, strong breaking capacity and short arcing distance. JZM1LE series circuit breakers can be equipped with alarm contacts, shunt releases, undervoltage releases, auxiliary contacts, rotary handle operating mechanisms, electric operating mechanisms and other accessories. JZM1LE series circuit breakers have multiple wiring methods such as front wiring, rear wiring and plug-in wiring. JZM1LE series circuit breakers can be installed vertically and horizontally.
