KSD303 系列 KSD303 SERIES 佛山通宝股份有限公司 佛山市通宝华龙控制器有限公司 FOSHAN TONGBAO CO.,LTD. TONGBAO HUALONG CONTROLS CO.,LTD. 单位 UNITS:MM FSTB MAKES LIFE BETTER 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. ◎ 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. ◎ 耐寒温度 Cold-resistant Temperature: -40℃ ◎ 温度特性类型 Class of Temperature Characteristics 常闭、常开 Normal close, normal open ◎ 最高动作温度及耐热温度 Max.
