Capillary Thermostats – DPDT

DPDT Capillary Thermostats

Double Pole, Double Throw Capillary Thermostats

Senasys offers the addition of a second switch, which opens the range of applications for a capillary thermostat, 352 series. The two switches can be any combination of a single pole, double throw (SPDT) automatic reset; or a single pole, single throw (SPST) manual reset. The 352 series differential can be factory set very close for a double pole application or widened out for multistage applications. The switch can be used for a combination of heating and cooling, or fan and limit, from one thermostat; or use it for three phase or double line breaks. The 352 series leaves applications wide open. The 352 series are rated up to 30 amps per switch.

These capillary thermostats have a temperature range between 0°-700°F, with a max ambient temperature of 250°. The temperature range determines when the capillary thermostat will close, or engage the electrical circuit, and when it will automatically reset, or open. These capillary thermostats can also be manually reset for when you need to call special attention to a temperature malfunction. The temperatures can be fixed or adjustable. Please consult factory for custom fixed temperature options.

Copper/Plated Copper or Stainless steel construction are available and all variations have multiple mounting options.

Custom options such as capillary tube lengths and custom temperature ranges are available. Please send a request for quote with your application details.
