Niglon RCD4-25/30-A 25A 30MA Type A 4P RCD

The Niglon RCD4-25/30-A is a 25A 30mA Type A four-pole RCD (RCCB) for three-phase (3P+N) circuits. It provides residual current protection across all four poles, disconnecting the supply on an earth-fault to protect against electric shock and fire.

Type A sensing responds to AC and pulsating DC residual currents, with a 10kA breaking capacity at 400/415V. Manufactured to BS EN 61008-1.
