CAM SWITCHES

(AC250V-10A,30A / DC125V-20A)

·All contact point of our cam switches are complete seal inside the main body and can add terminal safety cover(option).

·Special design the contacts of switches for current meter, when switching, contacts will keep close till switch process finished. By this design, we can protect CT perfectly.

·Contacts of cam switches are all perfect alignmented and with perfect cut off capability, use springs to provide high stress at the closed cotnacts, and all springs are isolated from power.

·Provide spring type automatic return、pull out operate model with obvious close/trip indicators for CB control.

零件(Part ) 材質(Materials)

本體(Body) 耐熱ABS樹脂 (Heat resistance ABS Resin)

凸輪(CAM) 縮醛樹脂 (Acetal Resin)

接點(Contact) 銀氧化鎘合金 (Silver-cadmium oxide alloy)

端子(Terminal) 黃銅 (Brass)

螺栓(Bolt) 碳鋼 (Carbon Steel)

彈簧(Spring) 不鏽鋼 (Stainless steel)

壽命 (Lifetime) 機械壽命 (Mechanical) above 500,000 times (switching freq : 20times/min.) 電氣壽命 (Electrical) above 100,000 times (switching freq : 20times/min.) 絕緣阻抗 (Insulation resistance) above 100MΩ (DC 500V. Meg)

接點阻抗 (Contact resistance) below 50mΩ (initial value) 耐受電壓 (Withstand voltage) AC 2,500V/min (50~60Hz)

Endurance 10~55Hz, 1.5㎜

Malfunction 10~15Hz, 1.0㎜

Endurance 30g (300 ㎨)

Malfunction 10g (100 ㎨)

操作力道 (Operating force) 560g

環境溫度 (Ambient temperature) -25℃ ~ +40℃

相對濕度 (Relative humidity) 45 ~ 85%

震動耐受度

(Withstand vibration) 衝擊耐受度

所有切換開關產品之接點部分均完全的密封在本體之中,並標配接線端子安全保護蓋。

針對電流表用開關之特殊設計,在接點切換過程中,原接點斷開前保持接通(具動作重疊),藉此可對 CT進行完善的保護。

開關的接點均完美對正且具自清動作,使用彈簧來使閉合接點保持高壓力,且彈簧不帶電。

提供自動彈簧複歸、拉出操作型式開關供斷路器操作使用,並具備清楚的投入/跳脫指示。
