Schneider Zelio vs ABB CM: Monitoring Relay Comparison
A function-by-function comparison of Schneider Zelio Control and ABB CM monitoring relays covering three-phase supply, voltage, current, level, temperature, module width, and measurement method.
The ABB CM-MSE (SKU: 1SVR550805R9300) is a thermistor motor protection relay (PTC) designed to protect electric motors from overtemperature damage by monitoring PTC thermistor sensors embedded in the motor windings. Rated at 4 A / 250 V with a 24 VAC supply and a single normally-open (1NO) output contact, the CM-MSE delivers reliable thermal protection in compact 22.5 mm DIN-rail format for control panels and industrial automation systems.
What sensor type does the CM-MSE work with?
The CM-MSE is designed exclusively for PTC (Positive Temperature Coefficient) thermistors embedded in motor windings, triggering the output contact when sensor resistance indicates an overtemperature condition.
What is the supply voltage of the CM-MSE?
The relay for thermistor protection CM-MSE operates on a 24 VAC control supply voltage.
What output configuration does the CM-MSE provide?
It provides one normally-open (1NO) output contact rated at 4 A / 250 V for integration into motor control or alarm circuits.
