Why Choose the Mersen CMS22W2 Auxiliary Microswitch Kit?
The Mersen CMS22W2, manufacturer item number B331201, is a two-auxiliary-microswitch kit designed for prepared three-pole Mersen Modulostar® CMS22 modular fuse holders. It enables remote indication of fuse-holder position or fuse operation within industrial control, protection and monitoring systems.
The kit allows status signals from a compatible CMS22 fuse holder to be connected to PLCs, alarm circuits, control relays or supervisory systems. This supports faster fault detection and improved equipment monitoring without requiring maintenance personnel to inspect every fuse holder manually.
Each auxiliary microswitch is suitable for low-current signalling from 1 mA at 4 V and medium-current circuits up to 5 A. With a rated insulation voltage of 250 V AC and Faston lug connections, the CMS22W2 provides a practical monitoring accessory for industrial switchboards and machinery panels.

Remote Fuse-Holder Status Monitoring
Auxiliary microswitches convert the mechanical position or operating status of a compatible fuse holder into an electrical signal. This signal can be used by a PLC, indicator lamp, alarm circuit or building management system to provide remote status information.
The Mersen CMS22W2 is designed for prepared three-pole CMS22 fuse holders and contains two microswitches within one accessory kit. When fuse-operation monitoring is required, compatible striker-equipped fuse links must be used so that the microswitch mechanism can detect fuse operation correctly.
Typical Applications
- Industrial control panels and switchboards.
- PLC-controlled machinery.
- Remote fuse-status monitoring.
- Alarm and fault-signalling circuits.
- Motor control centres.
- Power distribution equipment.
- OEM automation and panel-building projects.

Frequently Asked Questions
What is the Mersen CMS22W2 used for?
The CMS22W2 provides auxiliary electrical contacts for remotely monitoring the position or operating status of a prepared three-pole Mersen CMS22 fuse holder.
How many microswitches are included?
The CMS22W2 kit includes two auxiliary microswitches.
Which fuse holders are compatible with the CMS22W2?
It is designed for compatible, previously prepared Mersen Modulostar® CMS22 three-pole fuse holders.
Can the CMS22W2 be connected to a PLC?
Yes. Its auxiliary contacts can provide status signals to a compatible PLC, alarm circuit, relay or industrial monitoring system.
What is the maximum switching current?
The microswitches support medium-current switching up to 5 A, subject to the applicable voltage and utilisation category.
Are striker-equipped fuses required?
Striker-equipped fuse links are required when the microswitches are being used to detect fuse operation rather than only the mechanical position of the fuse holder.
