Why Choose the Mersen CMS141M Modulostar® Fuse Holder?
The Mersen CMS141M, item number Z331038, is a dependable single-pole modular fuse holder with an integrated microswitch, designed for 14 × 51 mm cylindrical fuse links. Part of the established Mersen Modulostar® CMS14 series, it provides reliable circuit protection and remote fuse-status signalling for industrial control panels, machinery and electrical distribution systems.
The integrated microswitch enables the fuse holder to provide an auxiliary electrical signal for remote monitoring when used with a suitable fuse link and control circuit. This allows fuse operation to be communicated to a PLC, alarm, indicator or supervisory system, helping maintenance personnel identify electrical faults more quickly.
Rated for operation at up to 690 V AC and 690 V DC, the CMS141M features a finger-safe IP20 construction under IEC requirements, including during fuse replacement. Its compact DIN rail-mounted format makes it suitable for panel builders and equipment manufacturers requiring secure fuse installation with remote status indication.

Reliable Circuit Protection with Remote Indication
Modular fuse holders provide a secure connection between cylindrical fuse links and the protected electrical circuit. When an overload or short circuit causes the correctly selected fuse link to operate, the circuit is interrupted to help protect cables, machinery and connected electrical equipment.
The microswitch fitted to the Mersen CMS141M allows an auxiliary status signal to be incorporated into a suitable monitoring circuit. This can help reduce fault-finding time by providing remote notification through a PLC input, alarm system or control-panel indicator.
Typical Applications
- Industrial control and automation panels.
- Remote fuse-status monitoring systems.
- Motor and transformer protection circuits.
- Machinery and OEM electrical equipment.
- Low-voltage switchboards and distribution panels.
- PLC alarm and supervisory control circuits.
