Bussmann TPL-BA Eaton Series Telecommunication Fuse, 70A 170Vdc

Bussmann TPL-BA Eaton Series Telecommunication Fuse, 70A 170Vdc

The Bussmann TPL-BA is an Eaton series TPL telecommunication fuse engineered for 170 Vdc, 70A DC power circuits requiring 100 kAIC interrupting capacity. This current-limiting, non-indicating fuse features a bolted blade end x bolted blade end configuration with silver-plated terminals for low-resistance, high-integrity electrical connections. Because the TPL-BA is current-limiting, it restricts peak let-through current and energy during a fault, helping protect conductors, bus structures, and sensitive downstream equipment. Built for telecommunication and DC power protection applications, the TPL-BA delivers dependable overcurrent protection in demanding power environments where high fault currents must be safely and quickly interrupted.

Key Features

• Amperage Rating: 70A continuous current rating suited for telecommunication DC power circuit protection.
• Voltage Rating: 170 Vdc rating engineered for demanding DC telecommunication power systems.
• Interrupting Rating: 100 kAIC interrupting capacity supports safe operation in high fault-current environments.
• Current-Limiting Design: Current-limiting operation restricts let-through energy to help protect downstream equipment, conductors, and bus structures.
• Non-Indicating Construction: Non-indicating fuse body consistent with standard Eaton Bussmann TPL-series telecommunication fuses.
• Terminal Configuration: Bolted blade end x bolted blade end termination provides a secure mechanical and electrical connection at both ends of the fuse.
• Silver-Plated Terminals: Silver-plated terminal finish enhances conductivity, reduces contact resistance, and helps resist corrosion at the connection points.
• Series: Part of the Eaton Bussmann TPL series of telecommunication fuses.
