Description

The Helo WE 40 is a multi-voltage contactor box that allows a Helo Pure or Elite Free control panel to switch electric sauna heaters of up to 15 kW. It provides the safe, reliable link between panel and heater, accepting a 230 V 3~ or 400–415 V 3N~ supply and switching SKLE, Laava and Octa heaters from 9–15 kW, Cup and Vienna heaters from 4.5–8 kW, and Havanna heaters from 4.5–9 kW. The box is designed to be installed outside the sauna room, where the cooler air protects the electronics, and it supports a sauna door switch, a remote-control contact and a switched output for the sauna light. The control panel and heater are sold separately: the WE 40 will not operate without a Helo Pure or Elite Free panel connected.

Features

  • Switches heaters up to 15 kW: Pairs a Helo Pure or Elite Free control panel with electric sauna heaters rated up to 15 kW.
  • Multi-voltage design: Accepts a 230 V 3~ or 400–415 V 3N~ three-phase supply to suit the installation.
  • Broad heater compatibility: Works with SKLE, Laava and Octa models from 9–15 kW, Cup and Vienna from 4.5–8 kW, and Havanna from 4.5–9 kW.
  • Mounted outside the sauna: Designed for installation outside the sauna room, where the lower temperature protects the electronics.
  • Door switch and remote ready: Registers a sauna door switch automatically and accepts a remote closing contact for switching the heater on and off.
  • Sauna lighting output: Carries a switched output so the sauna light can be controlled from the panel.
  • Control panel sold separately: Requires a Helo Pure or Elite Free control panel and a compatible heater, both sold separately.

Installation

Installation and maintenance must be carried out by a certified electrician, with the electricity supply isolated before any work begins. The contactor box is installed outside the sauna room using fixed cabling, with a connection box inside the sauna and a semi-fixed connection to the heater; a heat-resisting connection box and heat-resisting cables are required in the zones the manual specifies. All Helo D-body electric heaters paired with the WE 40 must be installed on a three-phase power supply. The installation and user manual and local wiring regulations must be followed.

Brand

Helo, founded in 1919, was the first manufacturer of electric sauna heaters, and its heaters and controls are made in Hanko, Finland. The company is part of the Sauna360 group.

Ordering note

Check your heater model, heater power and controller generation before ordering, and confirm that the matching control panel or contactor box is in place. Electrical installation must be carried out by a certified electrician.
