Fuse & Base:HDT1 Series Isolating Switch [Hits:271] 
HDT1 Series Isolating Switch
 
Application
 
Applying to making and breaking power turn-circuit of voltage 415V, frequency 50-60Hz,rated current less than 250A,acting as power switch, isolating switch and emergency switch. Because of special system of arc-contact and main- contact,HDT1 operates with high efficiency,safety and reliability, conforming to 415V(AC-23) and IEC947/3. GB14048.3 standard. Rotational operation and direct mechanical connection between handle and moving contact, on-off handle makes contact break and indicating place of contact. Panel and independent type installation are fitted with HDT1.
 
Technical parameter conform to IEC947-3、GB14048.3
