More Details

This LPN-RK-125 predates Bussmann's SP designation and is the original 125-amp, 250-volt Low-Peak Class RK1 fuse. It uses the 101–200A Class R knife-blade clip size common in 200A safety switches and panelboards on 208V and 240V systems. The dual-element construction handles motor starting current without oversizing, which makes it a common choice for motor branch circuits and small feeders, while the current-limiting design reduces fault energy downstream. Bussmann's current replacement is the LPN-RK-125SP, which shares the same dimensions. Check the interrupting rating printed on the label against your available fault current before installing.

See the manufacturer's data sheet for LPN-RK-125 specifications.

What is "surplus new"?

Surplus new means the item has never been installed or put into service. It may not arrive in its original packaging, but it has never been used.

What does "reconditioned" mean?

Reconditioned items have been inspected, cleaned, and tested to confirm they operate to the manufacturer's original specifications. Every reconditioned item we sell carries a one-year operational guarantee.

How fast will my order ship?

In-stock orders placed before 12pm PST usually ship the same business day via UPS, with tracking provided.
