Description The ThermoSphere Contactor Snubber Unit is an accessory for large electric underfloor heating circuits over 16A/3600W that are run on a single ThermoSphere thermostat. A single ThermoSphere thermostat is only rated for a maximum load of 16A/3600W, which roughly equates to 23m². So if the total load of your underfloor heating circuit exceeds 16A/3600W, and you want to control it from one thermostat, then you must install a suitably rated Contactor snubber.

The ThermoSphere Contactor Snubber is available in 3 different capacities: 25 Amp, 40 Amp and 63 Amp.
