Bussmann LPN-RK-1-8/10SP Low-Peak Class RK1 Dual-Element Fuse, 1.80A

Bussmann LPN-RK-1-8/10SP Low-Peak Class RK1 Dual-Element Fuse, 1.80A

The Bussmann LPN-RK-1-8/10SP is a Low-Peak Class RK1 dual-element, time-delay fuse rated 1.80A at 250 Vac, 125 Vdc, built for dependable overcurrent protection in large distribution switchboards, power panelboards, and motor control centers. Its current-limiting, dual-element construction pairs fast clearing of short-circuit currents with a time-delay response of 8s at 500% rated current, letting it ride through motor inrush and momentary overloads without nuisance opening. A 300 kAIC interrupt rating at 250 Vac and 100 kAIC at 125 Vdc gives this fuse the short-circuit withstand capability demanded by modern industrial and commercial electrical distribution systems.

Key Features

• Amperage Rating: 1.80A dual-element, time-delay fuse for precise circuit protection.
• Class RK1 Design: Current-limiting, time-delay construction for coordinated overcurrent protection in RK1 fuse clips.
• Dual-Element Construction: Two internal elements combine fast short-circuit clearing with a time-delay response for motor and transformer inrush tolerance.
• Response Time: 8s at 500% rated current allows the fuse to hold through momentary overloads and starting currents.
• Voltage Rating: 250 Vac, 125 Vdc for use across AC and DC distribution circuits.
• Interrupt Rating: 300 kAIC at 250 Vac and 100 kAIC at 125 Vdc for high short-circuit withstand capability.
• Electrically Isolated End Cap: Added safety feature for installation and service handling.
• Non-Indicating: Standard non-indicating fuse body construction.
