FAQs
The CM-MSS.32S uses screw terminals for both main and auxiliary circuits. Connecting capacity supports flexible 0.5 to 4 mm² conductors for the main circuit and 0.5 to 2.5 mm² for auxiliary connections, with appropriate stripping lengths (12 mm for main, 9 mm for auxiliary). This allows secure, maintenance-friendly terminations in compact panels.
Yes, the CM-MSS.32S is ATEX approved with an EU Type Examination Certificate TPS_18_ATEX_044254_0018_X. It also carries CE conformity and is supported by UL/CSA, CB, CCC, and CQC certifications, enabling compliant operation across many global regions and hazardous environments.
The device is powered from 24 V AC/DC and provides two SPDT outputs. Output current ratings are up to 4 A for AC-12 at 230 V and 4 A for DC-12 at 24 V, with protective fusing requirements and a minimum switching capacity of 24 V at 10 mA. This supports reliable signaling and interlock schemes in standard motor drives.
The CM-MSS.32S supports DIN rail mounting (TH35-15 or TH35-7.5) and screw-terminal wiring. It measures approximately 22.5 mm wide, 85.6 mm high, and 103.7 mm deep, with a net weight around 0.13 kg. These compact dimensions enable easy integration in space-constrained control panels.
The relay includes an auto, manual, or remote reset option after fault removal, along with sensor fault detection for short-circuits and interrupted wires. Its ATEX/CE compliance, rugged terminals, and high electrical/mechanical durability minimize service calls and extend motor life in challenging industrial environments.
