Bussmann TPL-BC Series Current-Limiting Telecommunication Fuse, 170 Vdc, 90A

Bussmann TPL-BC Series Current-Limiting Telecommunication Fuse, 170 Vdc, 90A

The Bussmann TPL-BC is an Eaton Bussmann series TPL telecommunication fuse engineered for current-limiting overcurrent protection in DC telecom power systems. Rated 170 Vdc, 90A, with a 100 kAIC interrupt rating, this fuse is built to safely clear high fault currents in demanding telecommunications and DC power distribution equipment where reliable, code-compliant overcurrent protection is essential. It features a non-indicating body design with bolted blade end X bolted blade end construction and silver-plated terminals that deliver a secure, low-resistance connection engineered for consistent long-term performance in central office and telecom power environments.

Key Features

• Voltage & Amperage Rating: 170 Vdc, 90A for DC telecommunications power circuits and equipment.
• Interrupt Rating: 100 kAIC, allowing the fuse to safely interrupt high-magnitude fault currents without compromising the circuit.
• Current-Limiting Design: Restricts peak let-through current and energy during a fault, helping protect downstream conductors and equipment from damage.
• Non-Indicating: Standard non-indicating body construction for straightforward field identification and replacement in telecom power panels.
• Terminal Configuration: Bolted blade end X bolted blade end design for a solid mechanical and electrical connection at both ends of the fuse.
• Finish: Silver-plated terminals for low contact resistance, improved conductivity, and enhanced corrosion resistance.
• Series: Part of the Eaton Bussmann series TPL telecommunication fuse family, purpose-built for DC power protection.
