Senasys designs and manufactures two different automatic reset thermostat switches – 25 Amps and 15 Amps at 120VAC.
Our heavy duty 25 Amp automatic reset thermostat switch is great for unique applications which require a faster response time or a lower contact resistance. The 15 Amp auto reset switches are available in many different mounting options and create a small footprint being a more cost effective solution.
The below options have a switching temperature range of 0-350°F. If you require a hotter temperature of 350°F-450°F, our ceramic style thermostat switches will be best for your application. Learn more here.
Senasys automatic reset thermostat switches are UL approved.
25 Amps – 2511 Series
These robust thermostat switches can be used in high current applications; carrying up to 25 amps at 240VAC, for over 100,000 cycles (30 Amps at 12VDC for 30,000 cycles). These switches are available in a single-pole, single-throw device. 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). The temperature range determines when the thermal switch will close, or engage the electrical circuit, and when it will automatically reset, or open. Over 40 standard temperature ranges are available, or we can easily design a custom temperature range to suit your application.
For unique applications exposed caps and gold contacts are also available. Exposed disc caps are available to provide a quicker response to temperature changes. Special black discs can be used to further improve the response to radiative heating in exposed units.
For low current and voltage applications gold contacts are available. These provide lower contact resistance and provide better performance for electronic duty loads.

15 Amps – 430 Series
The 430 Series is our 1/2″ automatic reset snap disc. These switches have a smaller footprint than the 2511 Series automatic reset thermostat switches, allowing for a lower cost. These switches are available in a single-pole, single-throw device, rated up to 15 Amps at 120VAC. The 430 snap disc thermostat switches have a temperature range of 35-350°F (2-175°C), with a differential temperature range of 15-100°F (-9-37°F). The temperature range determines when the thermal switch will close, or engage the electrical circuit, and when it will automatically reset, or open. Many temperature ranges are available, or we can easily design a custom temperature range to suit your application.
