MRO RGS4A aR Ultra-Fast Industrial Fuse, 125A 690V AC, for Semiconductor Protection - Pack of 10

MRO RGS4A 125A 690V aR Ultra-Fast Industrial Fuses for Semiconductor Protection

The MRO RGS4A is a specialized aR characteristic ultra-fast acting fuse, meticulously engineered to provide critical short-circuit protection for power semiconductor devices. Rated at 125A and 690V AC, this fuse is designed to operate with extreme speed, effectively isolating faults before they can damage sensitive and expensive components such as diodes, thyristors, IGBTs, and other power rectifiers. Its aR classification signifies its capability to interrupt only short-circuit currents, making it an ideal choice for circuits where overload protection is handled by upstream devices or where quick response to fault conditions is paramount. The RGS4A series ensures rapid fault clearing, minimizing arc energy and preventing cascading failures in complex power electronics systems. This product is supplied in a convenient pack of 10 pieces, suitable for maintenance, repair, and operational (MRO) stock or for multi-unit installations.
