Interface Relay Module Test Plugs

CM-MSS 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 rang 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 Technical Specification Manufacturer Part No. Supply Voltage Output Manual Reset Remote Reset Test Button Stock Number 1SVR430800R9100 24Vac/dc 1NO No No No 464-518 1SVR430801R1100 220-240Vac 1NO No No No 464-520 1SVR430810R9300 24Vac/dc 2CO Yes Yes No 464-570 1SVR430811R0300 110-130Vac 2CO Yes Yes No 464-574 1SVR430811R1300 220-240Vac 2CO Yes Yes No 464-568 1SVR430711R0300 110-130Vac 2CO Yes Yes Yes 464-564 1SVR430711R2300 380-440Vac 2CO Yes Yes Yes 464-558 1SVR430720R0400 24-240Vac/dc 1NO 1NC Yes Yes Yes 464-552 1SVR430720R0300 24-240Vac/dc 2CO Yes Yes Yes 464-546 Approvals Some products also have the ATEX approval for the use in hazardous areas.
