nVent RAYCHEM ACS-30-EU-PCM2-xx-20A Power & Control Module for ACS-30


ACS-30-EU-PCM2-xx-20A for distributed power and control in commercial and residential buildings

The RAYCHEM ACS-30-PCM2-xx-20A (PCM) is a modular power distribution and control panel for the ACS-30 control system.

The robust enclosure is approved for non-hazardous installation indoors. The PCM provides connection to the incoming power supply and power distribution & electrical protection to the heat tracing circuits. The PCM module also provides:

  • Ground fault monitoring
  • Line current monitoring
  • Alarm capability
  • RTD (Resistance Temperature Detector) input capability for each individual heating circuit


  • Decentralised PCMs can be located near to the trace heating system, with centralised control at the User Interface terminal (UIT).
  • Pre-installed with electrical safety and circuit protection devices to make installation quick and easy.
  • Control logic built-in to ensure a disconnection for the UIT does not result in loss of service.
