Residual current circuit breaker, 4P 63A 30mA 400V

【Safety Cut-Off】Protection against electric shock: Automatically cuts off in milliseconds in case of a leakage current exceeding 30 mA, preventing injuries and fire hazards in residential and commercial circuits.
【Dual Current Detection】Detects both sinusoidal AC leakage currents and pulsed DC residual currents, ensuring reliable tripping for modern devices with rectified loads and variable frequency drives.
【63A 4-Pole Switch】Rated at 63A 400V with 4-pole insulation, suitable for infrequent switching and motor starting, ideal for three-phase distribution boards and industrial control cabinets.
【IP20 Enclosed Enclosure】Enclosed construction prevents accidental contact with live parts; IP20 rating for indoor mounting in dry environments such as hotel technical rooms and control cabinets from the factory.
【Versatile Applications】Installation in homes, factories and hotels for the protection of branch circuits, protecting lighting circuits, power outlets and equipment power supplies against earth faults.
