Description

Advanced motor protection relay with versatile voltage range and ATEX certification.
The CM-MSS.31S is part of ABB's renowned range of thermistor motor protection relays, designed to provide advanced protection for motors. This relay operates at a rated control supply voltage of 24 - 240 V AC/DC, and features a 1 n/c + 1 n/o (SPDT) output with contacts rated at 250 V / 4 A. It is built to monitor PTC temperature sensors using a closed-circuit principle, ensuring reliable motor protection. The relay's sensor circuit is equipped with short-circuit and interrupted-wire monitoring capabilities, and it can be reset automatically, manually, or remotely after a fault has been cleared. Certified under the ATEX directive 94/9/EC, the CM-MSS.31S includes a reset/test button and is compatible with a sealable transparent cover to prevent unauthorized adjustments. Its screw connection technology utilizes double-chamber cage terminals for secure and efficient installation.
