DC Contactor ZLJM-400F Product Specifications Material used: AgCdO series (12) Contact rating (resistive load): 400A 48VDC/400A 250VAC

ZLJM-A DC contactor is mainly used to control DC circuits (main circuit, control circuit and excitation circuit, etc.).

A circuit breaker is a switching device that can close, carry and break current under normal loop conditions and can close, carry and break current under abnormal loop conditions within a specified time.

The world's first circuit breaker was born in 1885, it is a combination of a knife start and an overcurrent release.

The shunt is actually a resistor with a small resistance.
