Mersen DFC3LP - The adapter holds and safely encloses 1-1/2" x 13/32" midget or class CC fuses, similar to the DFC3M, but with a lower profile in height so it takes up less room where space is restricted. Made of clear polycarbonate, so the fuse can be identified when installed in a Mersen 303 series fuse block

Overview

The Mersen DFC3LP is a space-saving fuse adapter designed to securely hold and enclose 1-1/2" x 13/32" midget or Class CC fuses in industrial electrical systems. Engineered for applications where vertical clearance is limited, the DFC3LP features a significantly lower profile than comparable models like the DFC3M, making it ideal for compact control panels, motor control centers, and machinery enclosures. Its clear polycarbonate construction ensures durability, chemical resistance, and immediate visual inspection of the installed fuse—eliminating the need for disassembly during routine maintenance or troubleshooting. The adapter is specifically designed for seamless integration with Mersen 303 series fuse blocks, providing a precise and secure fit to maintain optimal electrical contact and prevent accidental dislodgement. With a robust design that resists impact and environmental factors common in industrial settings, the DFC3LP delivers reliable fuse protection without compromising on safety or performance. Compatible with Mersen’s 303 series fuse blocks, this adapter is a critical component for engineers and maintenance professionals prioritizing space efficiency and operational reliability in electrical protection systems.
