KSD303 KSD303 SERIES UNITS：MM KSD303；， 。、，； 。 ，KSD3032，：KSD303-A、KSD303-D。 KSD303 series snap-action defrost thermostat is a kind of miniature waterproof and hermetically seal bimetal thermal protector.
It is of single-pole single-throw structure and works under resistive load.
Thermostat is enveloped in cold-resistant and flame-retardant plastic tube or sealing gum for possible underwater applications.
The product series is widely used as heating compensated switch or automatic defrosting control switch in air-cooling frostless refrigerators.
According to different structures, KSD303 series is divided into two sub series as: KSD303-A, KSD303-D.
/BASIC TECHNICAL PARAMETER ◎ （） Rated Current: 3A, 6A, 10A (resistive) ◎ Insulation Resistance DC500VDC500V100MΩ。 With a DC 500V megger, borne DC 500V, the tested value is over 100MΩ.
◎ （） Dielectric Strength (in water) ，1500V 50Hz， ，。 In water, parts between the terminals and airproof wrap can bear 1500V 50Hz AC current, which is nearly sine wave, for one minute as bearing test.
Resulted no breakdown, no flashover.
