WEL7NL Series Miniature Leakage Circuit Breaker
Product number:
Classification:
Summary Description:
WEL7NL series miniature leakage circuit breaker is suitable for AC 50Hz, rated working voltage 230V, rated current 32A and below the circuit, used for indirect contact protection to people, as well as the construction and similar lines for overcurrent protection. It can also provide protection for fires caused by ground faults that persist due to the inaction of overcurrent protection devices; leakage circuit breakers with overvoltage protection can also protect against excessive voltage caused by grid faults.
