Description
The Trane FUS1889 is a dual element time delay fuse designed to protect HVAC electrical circuits by preventing damage from sustained overcurrents while tolerating harmless brief surges. It’s a critical safety component used in Trane and American Standard systems to safeguard control boards, motors, transformers, and other sensitive electrical parts.
Key Features
- Dual Element Construction: Time delay design allows short electrical surges (like motor startup currents) without blowing, while still protecting against prolonged overcurrent conditions.
- Voltage Rating: 240 VAC / 250 VAC — compatible with common HVAC line voltages.
- Current Rating: 60 A — interrupts the circuit when current exceeds 60 amps for a sustained period.
- Fuse Class: RK5 — high interrupting capacity suitable for HVAC and industrial power circuits.
- Cartridge/Blade Style: Clip in style fuse for easy service and replacement in fuse holders or panels.
- Safety Standards: Meets common UL/CSA electrical safety approvals (Class RK5 types).
