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.
