Raychem SBS-xx-SNR Control Panels

SBS-xx-SNR Control Panel Image

The SBS-xx-SNR control panel for pipe frost protection of sprinkler systems provides a totally integrated solution for the control of Raychem self-regulating heating cables for sprinkler applications.

The control panel comprises multi-control and multi-sensor thermostatic control and redundant circuit automatic switching capability in order to be compliant with the requirements of BS EN12845:2008.

The SBS-xx-SNR panels can switch 2-12 circuits of frost protection heating cables with up to 12 control and sensor inputs (one per primary circuit and one redundant circuit). The panel also includes electrical circuit protection devices (C-type circuit breakers and RCD protection) for safety and peace of mind.

The panels need only be connected to the 230Vac or 400VAC (Three Phase) power supply.


  • Increased safety through automatically switching redundant (Back up) heating circuit
  • All trace heating circuit protection built-in; no need for additional heater circuit protection devices.
  • EN60204-1 and EN60439-1 compliant multi-circuit control panels
  • Robust metal enclosure (RAL7035 – light Grey) housing with IP54 rating.
