Why Choose the Mersen CMS224 Modulostar® Fuse Holder?
The Mersen CMS224, manufacturer reference Q331099, is a robust four-pole modular fuse holder designed for 22 × 58 mm cylindrical fuse links. Part of the established Mersen Modulostar® CMS22 series, it provides reliable fuse protection and circuit isolation for three-phase electrical systems incorporating a neutral conductor.
The CMS224 features a finger-safe IP20 construction, including during fuse replacement when correctly installed and operated. This helps reduce the risk of accidental contact with live components while supporting safer inspection and maintenance within industrial control panels, switchboards and distribution equipment.
Rated at 125 A for applications up to 690 V AC or 690 V DC, the CMS224 is suitable for protecting motors, transformers, machinery, power distribution circuits and other industrial equipment. Its modular DIN rail format enables straightforward installation while the four-pole configuration provides coordinated fuse protection across multiple conductors.
