ZMB7LE-63 Modular (Integrated) Residual Current Circuit Breaker

ZMB7LE-63 Modular (Integrated) Residual Current Circuit Breaker is mainly suitable for AC distribution networks with a rated working voltage of 230V or 400V at 50/60Hz and a rated current of 63A. Used for indirect contact protection of people, and can also be used to prevent fire hazards caused by insulation damage to circuits and equipment, resulting in ground fault currents.

描述

DZ47LE-63 series leakage circuit breakers are suitable for AC 50Hz, rated working voltage single-pole two-wire, two-pole 230V, three-pole, three-pole four-wire, four-pole 400V, rated current up to 63A, used for indirect contact protection of people, and overcurrent protection of buildings and similar lines. It can also provide protection against fires caused by ground faults that persist due to the failure of overcurrent protection devices. Leakage circuit breakers with overvoltage protection can also protect against overvoltage caused by power grid faults.
This series of products has been increasingly used as backup protection for ground faults and direct contact and indirect contact electric shock in low-voltage power distribution systems.
The products comply with GB 16917-1 and IEC 61009-1 standards.
