Bussmann LPN-RK-5-6/10SP Low Peak Class RK1 Time-Delay Fuse, 5-6/10A

Bussmann LPN-RK-5-6/10SP Low Peak Class RK1 Time-Delay Fuse

The Bussmann LPN-RK-5-6/10SP is a Low Peak Class RK1 dual-element, time-delay fuse rated 5-6/10A, engineered to deliver dependable current-limiting overcurrent protection in demanding electrical distribution equipment. Rated 250 Vac, 125 Vdc with an interrupt rating of 300 kAIC at 250 Vac and 100 kAIC at 125 Vdc, this fuse is built for large distribution switchboards, power panelboards, and motor control centers where high fault-current withstand and reliable time-delay response are required. The non-indicating, electrically isolated end cap design supports safe handling and long-term performance in commercial and industrial installations.

Key Features

• Amperage Rating: 5-6/10A dual-element, time-delay fuse for precise, application-specific overcurrent protection.
• Fuse Class: Class RK1 construction for use in standard fuse clips, switches, and RK1-rated panelboards and switchboards.
• Voltage Rating: 250 Vac, 125 Vdc rating supports use across both AC and DC circuit applications.
• Interrupt Rating: 300 kAIC at 250 Vac and 100 kAIC at 125 Vdc for dependable performance under high fault-current conditions.
• Response Time: 8 seconds at 500% overload rides through motor starting current and transient inrush without nuisance opening.
• Dual-Element Construction: Two internal elements combine time-delay overload protection with fast current-limiting short-circuit response in a single device.
• Special Features: Electrically isolated end cap adds a layer of safety during installation and servicing.
• Fuse Indicator: Non-indicating design for standard fuse holder applications.
