Why Choose the Mersen CMS222M Modulostar® Fuse Holder?
The Mersen CMS222M is a robust 2-pole cylindrical fuse holder with two integrated microswitches, designed for reliable circuit protection and fuse-status monitoring in industrial control panels, machinery and low-voltage power distribution systems. As part of the established Mersen Modulostar® CMS22 series, it accepts 22 × 58 mm cylindrical fuse links and provides a compact modular solution for demanding electrical applications.
Rated at up to 125 A with an operational voltage of 690 V AC and 690 V DC, the CMS222M is suitable for high-capacity circuits requiring dependable fuse protection. Its two-pole configuration allows two conductors or phases to be protected within one coordinated assembly, while the incorporated microswitches enable remote signalling of fuse holder status.
The CMS222M features IP20 finger-safe protection, including during fuse replacement, helping reduce the risk of accidental contact with live components. Its DIN rail mounting format, modular construction and monitoring capability make it particularly suitable for industrial panel builders, OEM manufacturers and maintenance engineers.

Reliable Protection with Remote Fuse Status Monitoring
The Mersen CMS222M provides secure mounting and connection for two 22 × 58 mm cylindrical fuse links. When an overload or short circuit occurs, the installed fuse links interrupt the affected circuits according to their operating characteristics, helping protect cables, machinery and electrical equipment from damage.
Its two integrated microswitches allow the operating status of the fuse holder poles to be transmitted to control equipment, alarm systems or maintenance monitoring circuits. This enables faster fault identification and supports reduced downtime in automated industrial installations.
