MSR220KA PTC thermal relay

PTC-relay for the application as a protection device against inadmissible heating up at electrical equipment in areas with explosive gases (zones 1 and 2) and areas with combustible dust (21 and 22), e.g. for direct temperature-monitoring of explosion-proof motors EEx e and EEx d. Vertically arranged terminals. Each terminal remains accessible even if all others are already occupied.

  • SIL 1 according to IEC 61508
  • PL c according to ISO 13849
  • 1 PTC-resistor (thermistor) set, each 1...6 PTC-sensors
  • short-circuit monitoring of sensor-circuit
  • output-relay with 1 or 2 change-over contacts (co)
  • electronic reclosing lock (disconnectable)
  • integrated RESET-button
  • link for external reset
  • automatic reset at voltage recovery
  • RESET-Button with integrated LEDs for power-ON (green) and ALARM (red)
  • K-housing, vertically arranged terminals housing 22.5 mm wide
  • assembly on DIN-rail or with 2 screws M4 (option)
  • UL Recognized Component
  • Option: other supply voltages
