1SCA022627R0310 ABB 4A gG HRC DIN Fuse Link NH000 500V
ABB OFAF000H4 is a 4 A NH000 gG HRC DIN fuse link rated at 500 V AC with dual indication and a 120 kA maximum breaking capacity for full-range overload and short-circuit protection.
Why Choose the ABB OFAF000H4 4A gG HRC DIN Fuse Link?
The ABB OFAF000H4 is a compact 4 A HRC DIN fuse link designed for dependable full-range overcurrent protection in industrial and commercial electrical installations. Part of the ABB OFAF range, this fuse uses a gG utilisation category, providing protection against both overload and short-circuit currents.
Rated at 4 A and 500 V AC, the OFAF000H4 is suitable for protecting cables, conductors, distribution circuits and general-purpose electrical equipment. Its high-rupturing-capacity construction provides reliable interruption of high fault currents, with a maximum breaking capacity of 120 kA.
The compact NH000 / size 000 DIN format enables installation in compatible NH fuse bases and switch-fuse equipment. Dual indication supports convenient identification of fuse operation, while its low 1.5 W power loss supports efficient continuous operation in industrial electrical systems.
