KSD303系列
KSD303 SERIES
单位 UNITS：MM
KSD303系列突跳式化霜温控器是小型带外壳及防水保护的双金属片温控器；单刀单掷，工作于阻
性负载下。温控器密封于耐寒、阻燃的塑料管或密封胶中，可工作于水中；广泛应用于风冷式无霜电冰箱中作为
加热补偿开关或自动除霜控制开关。
按照不同的结构，KSD303系列划分为2个子系列，分别是：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 resis-
tive 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.
主要技术参数/BASIC TECHNICAL PARAMETER
◎ 额定电流（阻性） Rated Current: 3A, 6A, 10A (resistive)
◎ 绝缘电阻 Insulation Resistance
用DC500V绝缘电阻表加额定电压DC500V测定大于100MΩ。
With a DC 500V megger, borne DC 500V, the tested value is over 100MΩ.
◎ 电气强度（水中） Dielectric Strength (in water)
在水中，温控器的导线端子与塑料套之间能承受接近正弦波的1500V 50Hz交流电压历时一分钟的耐压试验，
不击穿，无闪络。
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.
