Bussmann TPL-BF Series Telecommunication Fuse, 170 Vdc, 150A, Current-Limiting

Bussmann TPL-BF Series Telecommunication Fuse, 170 Vdc, 150A, Current-Limiting

The Bussmann TPL-BF is an Eaton Bussmann series TPL telecommunication fuse engineered for demanding DC power protection applications. Rated 170 Vdc and 150A with a 100 kAIC interrupt rating, this current-limiting, non-indicating fuse is built to clear high fault currents quickly while limiting let-through energy to protect connected equipment. The TPL-BF uses a bolted blade end by bolted blade end terminal configuration with silver-plated terminal surfaces, giving installers a secure, low-resistance connection for high-current DC circuits. For telecommunication power plants, central office DC distribution, and other critical DC power systems, the Bussmann TPL-BF delivers the current-limiting overcurrent protection professionals rely on.

Key Features

• Voltage Rating: 170 Vdc, suited for DC telecommunication and power distribution circuits.
• Amperage Rating: 150A continuous current rating for demanding DC load protection.
• Interrupt Rating: 100 kAIC, providing high fault-current interrupting capability in DC systems.
