What is a disc thermostat?
Bimetal disc thermostats are thermally actuated switches. When the bimetal disc is exposed to its predetermined calibration temperature, it snaps and either opens or closes a set of contacts. This breaks or completes the electrical circuit that has been applied to the thermostat.
How do you reset a snap disk thermostat?
If it’s a manual reset thermostat switch, press the red button found on the thermostat switch to reset. Manual reset thermostat switches will not reset by themselves, and require human intervention to reset. If it’s a one shot thermostat switch, the switch needs to be replaced.
What is KSD301?
KSD301 series snap-action bimetal thermostat is a kind of miniature hermetically sealed bimetal thermostat (1/2″ disc). It is of single-pole single-throw structure and works under resistive load.
Which of the following are the two main types of thermostats?
Thermostats come in two basic types: low-voltage and line-voltage. The low-voltage system uses gas, electricity or oil – best suited to controlling the current of air. These thermostats are ideal for unitary power systems and water heating systems.
What does a snap disc do on a pellet stove?
This part may be called a limit switch, snap switch, or snap disc. These temperature sensing switches serve as a safety feature and typically control auger motors, blowers, and other major components in your stove. Depending on the brand and model, you may have multiple high and/or low limit switches.
What does a snap disc do?
Snap Disc, or snap switch thermostats are bimetal mechanical thermostats that function via the thermal expansion and contraction of a bimetal disc that “snaps” from a convex to a concave shape at a set temperature. When the disc “snaps”, it either completes or interrupts a circuit.
What is the difference between ksd201 and ksd301?
It will fit and do the job but it is a little different. The KDS201 is a single use thermal fuse used for equipment safety. When it reaches the rated temperature it blows like a fuse and must be replaced. The ksd301 are bi metallic thermostats, so they reset after they cool down.
How do I know what kind of thermostat I have?
The fastest way to see your thermostat model number is to look for it on your thermostat ID card. If you do not have a product ID card, the fastest way to find the model number is by removing the thermostat from the wall-plate.
What is the temperature of the disc thermostat?
1/2″ Disc Thermostat, US-602SYSHAS45140F30, Closes on rise 140°F ± 7°F, Resets at 110°F ± 11°F, Solder terminals, Surface mount bracket, 45deg orientation 1/2″ Disc Thermostat, US-602SYBVAS90140F30, Closes on rise 140°F ± 7°F, Resets at 110°F ± 11°F, .250″ Vertical quick connects, Surface mount bracket, 90deg orientation
How does a disc thermostat work?
Contacts will close or open on temperature rise when the surface or ambient temperature increases to the snap point of the calibrated bi-metal disc. These disc thermostats are retained by a metal heat conducting sensing cap and are all single pole, single throw non-adjustable switches.
What types of thermostats do you offer?
Designed to meet the cost, size and features of your application. We offer 1/2″ (15 Amp), 3/4″ (25 Amp) and hermetically sealed thermostats. Our selection includes phenolic, polyester, and ceramic body styles, a variety of mounting options and terminal configurations. Custom designs available upon request.
What is a single pole disc thermostat?
These disc thermostats are retained by a metal heat conducting sensing cap and are all single pole, single throw non-adjustable switches. To provide flexibility for customer specific applications, we offer a variety of terminal and mounting configurations.
