Bussmann 170M3764 High Speed Square Body Fuse, Class aR, 160A/700V
The Bussmann 170M3764 is an Eaton Bussmann series high speed square body fuse engineered for demanding semiconductor protection duty. Rated 700V (UL) / 690V (IEC) at 160A with a 200 kAIC interrupt rating, this Class aR (accompanied semiconductor protection) fuse uses a square body design with center bolted tags and blade end x blade end termination for secure, low-resistance mounting in power electronics and drive circuits.
Key Features
- Amperage Rating: 160A for reliable overcurrent protection in high-power circuits.
- Voltage Rating: 700V (UL), 690V (IEC) for use in high-voltage AC power electronics systems.
- Interrupt Rating: 200 kAIC delivers high fault-current interrupting capability for demanding installations.
- Fuse Shape: Square body with center bolted tags and blade end x blade end termination for a compact, high-current connection.
- Utilization Category: Class aR (accompanied semiconductor protection) for coordinated protection of power semiconductors.
- Clearing I2t: 7500 at 660V; Pre-Arc I2t: 1100, supporting fast, predictable clearing performance.
- Watt Losses: 30W, a factor to account for in enclosure thermal design.
