When the underfloor heating circuit load exceeds the maximum capacity of the thermostat (normally 16A / 3,600 Watts) a suitably rated contactor must be used.

This 20 Amp rated contactor will switch a load of up to 5,400 Watts.

The DIN rail mounting contactor can be installed into one of Vysal's enclosures for DIN rail devices

A manual override enables the temporary setting of the contactor in either the on or off position in addition to normal automatic operation.

When a contactor is mounted alongside an MCB of greater than 10 amp current rating or two contactors are mounted alongside an MCB or side by side, it is necessary to insert a blank module between them.

We offer the MK 6220s and the IC20 from Control Gear Direct (much cheaper)
