Product Description

The BUSSMANN LPN-RK-SP Series fuse is a Class RK1 time-delay blade fuse rated at 350 A, 250 V AC, and 250 V DC. This non-indicating fuse, manufactured by BUSSMANN under part number LPN-RK-350SP, is designed for overcurrent protection in industrial electrical systems.

Frequently Asked Questions

What is the BUSSMANN LPN-RK-350SP fuse used for?

The BUSSMANN LPN-RK-350SP is a Class RK1 time-delay blade fuse rated 350 A, 250 V AC/DC. It provides overcurrent protection in industrial electrical systems, such as motor circuits, feeders, and branch circuits, where high inrush currents require a time-delay characteristic.

What are the specifications of the BUSSMANN LPN-RK-350SP fuse?

The BUSSMANN LPN-RK-350SP is a Class RK1, time-delay, non-indicating blade fuse. It is rated 350 A, 250 V AC and 250 V DC. It belongs to the LPN-RK-SP series and is manufactured by BUSSMANN under MPN LPN-RK-350SP.

Where to buy the BUSSMANN LPN-RK-350SP fuse worldwide?
