Bussmann S505-1.25-R Time Delay Fuse

Bussmann S505-1.25-R Time Delay Fuse

Precision Overload Protection for Demanding Circuits

Engineered for reliability, the Bussmann S505-1.25-R is a 1.25-amp time-delay fuse designed to safeguard sensitive electronic equipment from damaging overloads and short circuits. Its controlled delay feature allows brief current surges (like motor startups or inrush currents) to pass safely while interrupting sustained faults. Ideal for industrial controls, HVAC systems, and power supplies.
