SST6-RSW 6kW Soft Start Controller with Remote Switch Input

Product Code: SST6-RSW

The SST6-RSW Soft Start Controller is a fully weatherproof solution for controlling up to 6kW of electric heaters (such as infrared quartz halogen).  Designed to augment an existing simple on/off switch the unit will prolong the life of the heating elements through soft-start and soft-stop technology, thus reducing maintenance costs.

The SST6-RSW is operated by connecting any suitable latching action switch (e.g. a conventional light switch**) which delivers greater flexibility in the style and placement of controls.  When turned on, power is gradually applied to the heater over 3 seconds so avoiding large inrush currents and reducing stress to both the heating element and the electrical supply. When the switch is returned to the off position, the heater is turned off in a similar manner.

Designed for safety the remote switch connection terminals are low voltage and isolated from the mains supply.  This ensures that the control switch remains safe for use at all times.

The unit is designed for outdoor installation, rated to IP65 and housed in a robust high-quality polycarbonate enclosure. All connections are made through preinstalled cable glands, and wall mounting is achieved via pre-drilled holes in the enclosure which maintain its ingress protection rating

The SST6-RSW can control a maximum load of 6kW and is supplied with 2 sets of integrated terminal blocks and cable glands for ease of installation. If more than two loads are to be connected to the timer this can be completed via a suitable junction box.

Typical applications for the 6kW Soft Start Controller include:

  • Warehouse infrared halogen heaters
  • Workshops
  • Garages and hangers
  • Agriculture and stabling
  • Churches
  • Pub and beer gardens
  • Restaurants and Hotels
  • Patio and gardens
  • Smoking shelters
  • Outdoor event heaters

* Based on typical usage estimates.
