Bussmann TPL-CN Series 300A Telecommunication Fuse, 170 Vdc, 100 kAIC

Bussmann TPL-CN Series 300A Telecommunication Fuse, 170 Vdc, 100 kAIC

The Bussmann TPL-CN Series 300A Telecommunication Fuse is an Eaton Bussmann series TPL fuse purpose-built for DC telecommunication power protection. This current-limiting, non-indicating fuse is rated 170 Vdc, 300A, and 100 kAIC interrupt rating, giving central office and data center power systems a dependable overcurrent protection device. The fuse uses a bolted blade end x bolted blade end terminal configuration with silver-plated terminal surfaces, designed for a secure, low-resistance mechanical and electrical connection in bolted-type fuse mounting hardware.

Key Features

• Amperage Rating: 300A rating supports high-capacity telecommunication and DC power distribution circuits.
• Voltage Rating: 170 Vdc rating is matched to DC telecommunication power plant applications.
• Interrupt Rating: 100 kAIC interrupt rating combined with current-limiting performance helps reduce fault energy let-through on high-availability circuits.
• Current-Limiting Design: Limits peak let-through current and energy during a fault condition, helping protect downstream equipment and conductors.
• Non-Indicating Construction: Standard non-indicating body style for straightforward fuse identification and replacement during maintenance.
• Terminal Configuration: Bolted blade end x bolted blade end design for a secure mechanical and electrical termination at both ends of the fuse.
• Silver-Plated Terminals: Silver-plated terminal surfaces support consistent conductivity and long-term connection reliability.
• Eaton Bussmann Series TPL: Part of the Eaton Bussmann series TPL telecommunication fuse family engineered for DC power protection.
