Product Description

MERSEN Fuse Blocks for UL Class J Fuses.

Frequently Asked Questions

What is a MERSEN fuse block used for?

A MERSEN fuse block securely mounts and connects UL Class J fuses in industrial circuits, protecting equipment from overcurrent. It is used across machining, electrical, and power transmission systems where reliable fuse retention and safe disconnection are required.

What are the specifications of the MERSEN 64001J fuse block?

The MERSEN 64001J is a 1-pole, open block design fuse block rated for 600 V AC. It uses a box lug terminal and is non-indicating. It is designed for UL Class J fuses, ensuring proper fuse alignment and electrical continuity in industrial control panels.

Where to buy MERSEN fuse blocks worldwide?
