Disc Self Hold Thermal CUT OUT & Resistor Combination

KSD301 / KSD302 thermostat disc self hold thermal cut out is a safety device that prevents a heater from overheating or faulting:

How thermostat disc self hold thermal cut out works?
When the temperature reaches a predetermined level, the thermostat opens, and the contacts remain open. The only way to reset the device is to remove power from the circuit.

thermostat disc self hold thermal cut out Benefits:
A self hold thermal cut out offers extra safety compared to an automatic reset device, and it works similarly to a manual reset device without the need for a push button.
Types of self hold thermal cut outs
Some types of self hold thermal cut outs include:
KSD301 / KSD302: A combination of a thermostat and a resistor, where the resistor is located below the thermostat’s contact arm.
KSD301 / KSD302 EAW SO: Similar to an auto-reset type, but with an internal heating resistor that prevents the bimetal disc from auto-resetting.
KSD302-T: A 1/2” disc PTC thermal cut-out that features easy mounting, rapid heat transmission, high durability, e alta precisione.
