SECURITY THERMOSTAT

Type: 301

CHARACTERISTICS
301 series snap-action thermostat is a kind of miniature hermetically sealed bimetal thermal protector. It is of singlepole single-throw structure and works under resistive load.
The bimetal disc will snap instantly when subjected to certain temperature to cause quick switching action of contacts via mechanical function and to interrupt or complete a circuit.
This device has the advantage of fixed working temperature needed no adjustment, reliable and agile action, long service life as well as less radio disturbance.

APPLICATION
301 series is in wide use in a great variety of compact type home appliances, such as coffee makers, toasters, microwave ovens, etc.
