Why Choose the Mersen CMS222I Modulostar Fuse Holder?
The Mersen CMS222I, item number D331134, is a high-performance two-pole modular fuse holder designed for safe and reliable protection of industrial electrical circuits. As part of the Mersen Modulostar® CMS22 series, it accepts 22 × 58 mm IEC cylindrical fuse-links and is suitable for protecting motors, transformers, low-voltage distribution systems and industrial control equipment operating at up to 690 V AC or 690 V DC.
Rated for a maximum current of 125 A, the CMS222I features an integrated visual blown-fuse indicator, allowing maintenance personnel to quickly identify an operated fuse without removing the fuse-link. The finger-safe IP20 construction provides additional protection during both normal operation and fuse replacement.
Its rugged thermoplastic construction and DIN rail mounting make the CMS222I ideal for OEM machinery, automation equipment, switchboards and industrial control panels. The modular design also supports future expansion using Mersen multi-pole assembly kits and optional microswitch accessories where remote indication is required.
