£28.48
The Mersen CMS14W3, item number Z331176, is a purpose-designed three-microswitch accessory kit for compatible Mersen Modulostar® CMS14 modular fuse holders. It enables remote electrical signalling from multi-pole fuse-holder assemblies, helping operators and maintenance teams monitor fuse status through control panels, alarms, PLCs and supervisory systems.
Supplied with three auxiliary microswitches, the CMS14W3 is suited to compatible three-pole CMS14 installations where individual pole monitoring is required. When correctly installed with suitable fuse links and associated control circuitry, each microswitch can provide an electrical status signal to support faster fault identification and more efficient system maintenance.
The accessory is designed specifically for the Mersen Modulostar® CMS14 range, which accommodates 14 × 51 mm cylindrical fuse links. Its compact construction allows remote indication functionality to be added without compromising the organised modular layout of industrial control panels and electrical switchboards.
Auxiliary microswitches convert the mechanical operation of a compatible fuse or fuse-holder mechanism into an electrical signal. This signal can be connected to an indicator lamp, alarm circuit, PLC input or supervisory control system, allowing circuit status to be checked remotely.
The Mersen CMS14W3 provides three separate microswitches for compatible multi-pole installations. This can simplify fault diagnosis in three-phase systems by allowing each protected pole to be monitored, reducing the need for manual inspection of every fuse holder during a system fault.
