FI block Vigi NG125, 300-3000mA. 4-pole, nominal current 125A, type A-SI, operating voltage (Ue) 230-240V, 400-415V, insulation voltage (Ui) 690V. FI blocks Vigi NG125 are mounted on the right-hand side of NG125 series miniature circuit breakers. In combination they form a FI/MCB with the following functions: additional protection in the event of direct contact (30 mA), fault protection in the event of indirect contact (u 300 mA), fault protection in the event of indirect contact, 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, e.g. B. caused by switching on electronic ballasts, EMC filters, high number of PCs, voltage peaks (lightning, switching operations). Additional auxiliary modules that can be connected in series (optional) - display of switch position, fault tripping, shunt release, undervoltage release, overvoltage release.
