Bussmann 170M3560 Eaton Series High-Speed Square Body Fuse, Class aR
The Bussmann 170M3560 is an Eaton Bussmann series high-speed square body fuse engineered for semiconductor protection in demanding industrial power circuits. Rated 700V (UL) and 690V (IEC) with a 63A amperage rating and a 200 kAIC interrupting rating, this Class aR fuse features a flush, square body construction for compact panel mounting. Its aR utilization category (accompanied semiconductor protection) makes it well suited for coordinated protection of semiconductor devices where fast clearing performance is critical.
Key Features
- Amperage Rating: 63A rated current delivers reliable overcurrent protection in industrial power circuits.
- Voltage Rating: 700V (UL) / 690V (IEC) supports use across both UL and IEC-rated systems.
- Interrupting Rating: 200 kAIC provides high interrupting capacity for demanding fault-current environments.
- Class aR Construction: Utilization category aR (accompanied semiconductor protection) for coordinated use with semiconductor devices.
- Fuse Shape: Square body with flush end contacts for compact, space-saving installation.
- Clearing I2t: 770 at 660V for predictable let-through energy during fault clearing.
