The CM-MSS.22P operates from a 24 V AC/DC control supply, enabling flexible integration with existing control circuits and two SPDT outputs to drive auxiliary devices while preserving simple wiring and reduced panel depth. This feature translates to faster commissioning and lower wiring errors, which is critical for OEMs delivering machine uptime guarantees in manufacturing lines. The integrated sensor circuit continuously monitors PTC thermistors, enabling early fault detection and prevention of motor windings damage; the tangible business impact is extended motor life, fewer unplanned outages, and lower replacement costs in conveyors and pumps. With auto, manual, or remote reset options, maintenance crews can recover quickly after a fault, minimizing production interruption and service calls. The sealable transparent cover accessory adds security in harsh environments, protecting critical protection settings from unauthorized changes. Easy Connect push-in terminals and screwless connections cut install time and improve reliability when field wiring is dense. DIN rail mounting TH35-15 or TH35-7.5 simplifies panel design and future upgrades, while compact dimensions fit legacy and modern control panels. The device adheres to UL/CSA, CE, and RoHS standards, supporting global deployments without redesign. Compatibility with 24 V DC and 24 V AC control schemes ensures broader applicability across machine tools, pumps, and material handling systems.

FAQs
Yes. The CM-MSS.22P supports DIN rail mounting on TH35-15 and TH35-7.5 rails per IEC 60715. This simplifies panel design and enables quick field upgrades without custom brackets. Wire terminals use screwless push-in technology for fast, reliable connections. The mounting option reduces overall panel depth and improves serviceability in compact control cabinets.
The device provides 2 c/o SPDT outputs with rated operational current of 4 A at 230 V AC (AC‑12) and 4 A at 24 V DC (DC‑12). It is rated for auxiliary circuit operation at 250 V AC and supports minimum switching capability of 24 V at 10 mA, ensuring reliable switching for contactor coils and signaling circuits in motor drives.
Ideal for motor protection in pumps, conveyors, rolling mills, and machine tools where PTC thermistor sensors monitor winding temperature. Its 24 V control, SPDT outputs for signaling, and remote/manual reset capabilities make it suitable for OEM equipment and automation panels requiring reliable motor protection with fast fault isolation.
Certified to CE and UKCA for the European market, with UL/CSA recognition for North America. It also aligns with CAN/CSA and IEC/EN standards such as IEC 60947‑5‑1 and IEC 60947‑8, and complies with RoHS and REACH regulations. This broad certification support facilitates global deployment and supplier audits in regulated industries.
The CM-MSS.22P provides automatic, manual, or remote reset after a fault is cleared, enabling flexible maintenance workflows. A sealable transparent cover is available to prevent unauthorized changes, and Easy Connect push-in terminals accelerate field servicing. These features collectively reduce mean time to repair and lower labor costs in high-availability applications.
