Introduction

Littelfuse MEGA SN Series 70V bolt-down sealed waterproof fuse holders are an ideal solution for high-current, series, main circuit, or branch circuit protection in harsh or hazardous environments. Featuring AssureLatch sealed forced-latch technology, the fuse holder design ensures waterproof and flame-resistant functionality. The waterproof fuse compartment within the fuse holder assembly prevents fuse corrosion.

The base includes M6 mounting holes and M6 mounting slots for secure installation, with dimensions matching similar fuse holders, making it simple to upgrade from an unsealed to a sealed fuse holder. A built-in tether between the fuse holder base and cover keeps components connected during maintenance.

The MEGA SN Series sealed fuse holders are available with or without a pre-installed MEGA high-current bolt-down fuse.
