Schneider Electric 19101 FI-Block Vigi NG125, 4P, 125A, 30mA, Typ A, SI

RCD Block Vigi NG125, 30mA. 4-pole, nominal current 125A, Type A-SI, operating voltage (Ue) 230-240V, 400-415V, insulation voltage (Ui) 690V. RCD blocks Vigi NG125 are mounted on the right side of the NG125 series circuit breakers. They thus form a combined RCBO with the following functions: additional protection upon direct contact (30 mA), fault protection upon indirect contact (up to 300 mA), fire protection (300 mA). The SI version prevents unwanted tripping in systems where high availability is required (e.g., telecommunications, hospitals, infrastructure, data centers). It guarantees high electrical immunity to transient leakage currents, for example, caused by switching operations of electronic ballasts, EMC filters, a large number of PCs, voltage spikes (lightning, switching operations). Additional auxiliary modules that can be attached (optional): indication of switch position, fault tripping, shunt trip, undervoltage release, overvoltage release.
