ABB CM-MSS.41S Thermistor Motor Protection Relay, 1 sensor circuit for PTC resistor sensors type A, Din Mount, Product Code : 1SVR730712R1200

Thermistor Motor Protection Relay, 1 sensor circuit for PTC resistor sensors type A, Auto, manual or remote reset, 2 c/o (SPDT) 1NO & 1NC output 4.0A /250V, control supply voltage of 24 - 240 V AC/DC, LED Indication, Screw terminals Connection, Din Mount Product Code : 1SVR730712R1200

Features:
• The thermistor motor protection relay CM-MSS monitors the winding temperature and thus protects the motor from overheating, overload and insufficient cooling in accordance to the product standard IEC 60947-8, control units for built-in thermal protection (PTC) for rotating electrical machines.
• The CM-MSS.41S belongs to the CM-MSS thermistor motor protection relay range. It operates with a rated control supply voltage of 24 - 240 V AC / DC and has a 2 c/o (SPDT) output with contacts rated at 250 V / 4 A.
• It features one sensor circuit to monitor PTC temperature sensors and works according to the closed-circuit principle.
• The sensor circuit of this CM-MSS.41S is short-circuit (configurable), as well as interrupted-wire monitored and can be reset automatically, manually or remotely after the failure has been removed
• This protection relay is certified according to the ATEX directive 94/9/EC and is equipped with a reset / test button.
• The non-volatile fault storage and the short circuit detection can be enabled/disabled via DIP switches.
