  • EAN:
    4013614496516
  • Catalog Description:
    CM-MSS.21P Therm. motor protec. relay 1n/o+1n/c, 24-240VAC/DC
  • Long Description:
    The CM-MSS.21P 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 1 n/c + 1 n/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 the CM-MSS.21P is short-circuit, as well as interrupted-wire monitored and the relay will be reset automatically after the failure has been removed. This protection relay is certified according to the ATEX directive 94/9/EC. A sealable transparent cover for protection against unauthorized changes is available as accessory. The device offers maintenance free Easy Connect Technology with push-in terminals.
