3/4″ Bi-Metal Snap Disc Thermostats
Senasys 3/4″ Snap Disc Thermostats are quality-engineered thermal sensors specifically designed for a variety of applications.
These robust thermostat switches can be used in high current applications; carrying up to 40 amps-240 Volts, for over 100,000 cycles. A 3/4″ bimetal thermodisc at the heart of our thermostat is set to a precise temperature range within 0°-350°F (-18°-176°C). Temperature calibrations are preset. To insure that a safe combination of thermostat and application is achieved, the purchaser must determine product suitability for their individual requirements.
Senasys 3/4″ Thermostat Switches are available as three different types:
- Automatic Reset
- Epoxy Sealed Automatic Reset
- Manual Reset
- Single Shot

Manufactured to individual temperature specifications • Available in a variety of terminal and mounting configurations
All units are subject to 100% mechanical and thermal inspection.
Recognized by UL and CUL • Meets UL Standard 873 and 353
made in u.s.a.
Designed & manufactured in Eau Claire, WI, U.S.A.
This type of control can be built to either open or close its electrical contacts as the temperature increases. Once the temperature of the bimetal disc has returned to the specified reset temperature, the contacts will automatically return to their original state.
Epoxy Sealed (Single Pole, Single Throw)
Senasys manufactures a 3/4″ epoxy sealed snap disc thermostat, 2570 series, which is a unique thermostat switch designed for extended use in extreme environments.
Epoxy Sealed (Single Pole, Double Throw)
The 416 series is the SPDT version of our encapsulated ¾” automatic reset snap disc. The encapsulated design creates a seal especially designed for refrigeration, air conditioning, and industrial applications, requiring a moisture and dust resistant enclosure.
This type of control is available only with electrical contacts that open as the temperature increases. The contacts may be reset by manually pushing on the reset button after the control has cooled below the open temperature calibration.
The single shot thermostats are specifically designed as high limit devices for applications where automatically resettable thermostats are not desirable.
