FAQs
The CM-MSS.12P is designed for DIN rail mounting on TH35 contacts, supporting TH35-15 and TH35-7.5 profiles. It uses maintenance-free Easy Connect push-in terminals for fast, reliable wiring, reducing install time and mis-wires. Its compact footprint (22.5 mm width, 85.6 mm height, 103.7 mm depth) fits compact control cabinets and multi-device assemblies without sacrificing clearance or service access.
The relay operates with a rated control supply voltage of 24 V AC/DC and provides 1 c/o SPDT output. It supports AC-12 4 A and DC-12 4 A (230 V / 24 V respectively) with appropriate minimum switching capacity of 10 mA at 24 V. It offers 4 kV impulse withstand between outputs, 300 V insulation across circuits, and IP50 housing for enhanced reliability in industrial environments.
Yes. The CM-MSS.12P is specifically designed for thermistor motor protection via a PTC sensor circuit, auto-reset functionality, and a robust SPDT output. Its 24 V control, DIN-rail mounting, and compatibility with typical motor control schematics make it ideal for conveyors, pumps, and other electromechanical systems where overheating protection and automatic fault recovery reduce unplanned downtime.
This device carries CE and UKCA marks, and UL/CSA recognition, with additional declarations for CCC, CB certificates, and RoHS compliance. It meets IEC/EN 60947-5-1 and related standards, enabling safe integration into global automation projects. For regulated industries, these certifications help satisfy procurement and safety documentation requirements.
The protected motor circuit benefits from auto reset after fault removal, keeping downtime minimal while avoiding manual reset procedures. With maintenance-free Easy Connect push-in terminals and screwless terminations, installation stays reliable over time, reducing field service visits. Long mechanical durability (30,000,000 cycles) and electrical durability (100,000 AC-12 cycles) translate into lower lifecycle costs and improved asset availability.
