Description
The York S1-025-32771-001 Dual Time Delay Fuse is an overcurrent protection part that secures low-amperage control circuits by allowing brief inrush currents to pass while interrupting sustained fault currents that exceed its 0.5-ampere rating. Its dual-element construction absorbs temporary current spikes during startup through one element, while a second thermal element melts and breaks the circuit when an overload persists beyond a safe duration at up to 600 volts. Seated in the designated fuse holder or fuse block within control panels, air handlers, and furnace units across HVAC systems, it fits directly into the low-voltage control circuit.
