Product Description
ABB CM-MSE Thermistor Motor Protection Relay
Overview
The ABB CM-MSE is a thermistor motor protection relay from the CM series, designed to provide motor protection by monitoring the temperature of motors using PTC temperature sensors or bimetals. It is equipped with a single sensor circuit for temperature monitoring and includes an auto-reset feature. The relay operates with a 110-130 V AC control supply voltage and features a 1 n/o (normally open) output contact rated at 250 V / 4 A.
Key Features
-
