ASJ10-LD1A leakage relay
Acrel ASJ series post-current action relays, low-voltage circuit breakers, or low-voltage contactors can be combined into post-current generation devices, primarily used for TT and TN system distribution circuits with 50 Hz AC and a rated voltage of 400 V or less. ASJ series post-current action relays are used for ground fault protection of electrical circuits to prevent equipment damage and fires caused by ground fault currents. They also provide indirect contact protection against the risk of electric shock.
