ABB Temperature Monitoring Relay, 1 Phase, DPDT, DIN Rail

Some products also have the ATEX approval for the use in hazardous areas. CM-MSS Series Thermistor Motor Protection Relays. Heavy duty starting Increased switching frequency High ambient temperature Insufficient cooling Break operation Unbalance. The CM range of thermistor motor protection relays are used to control motors equipped with PTC temperature sensors. The PTC temperature sensors are incorporated in the motor windings to measure the motor heating. This enables direct control and evaluation of the following operating conditions:. Main features include: Dynamic interrupted wire detection Wide control supply voltage range for this series 24-240 V AC/DC Short circuit monitoring of the sensor circuit Non-volatile fault storage Remote reset Screw connection technology or Easy Connect Technology available. Single Sensor Input Version Wire Break Detection
