Differential Circuit Breaker VД1-63 25A 30mA for Enhanced Electrical Safety

A quick-acting protective switch reacting to differential current, without built-in overcurrent protection. Designed to protect people from electric shock in case of accidental unintentional contact with live parts of electrical installations and prevents fires due to leakage currents to earth. It does not have its own power consumption and has high mechanical resistance to wear and tear.
