HR6 Fuse Switch Disconnector
|
| Application |
| HR6 series fuse type isolating switch are mainly used in rated voltage AC 380V and 660V(45-62Hz), conventional free air heating current to 630A power distribution and motor circuit, which possess high short circuit, used as power supply switch, isolating switch, emergency switch and for circuit protection. Usually not used as open/close every single motor. |

| Structural Features |
The switch is composed of base, cover and interrupter, made from arc resistance plastic, all plastics structure. The static contact is install on the base, the interrupter is easy to remove and mount, each interrupter has inside & outside room, adopts multi-chip metal are extinguishing grating, increased the are ability, also improved the lifetime for contact.
The fuse-link of NT mode is installed inside the cover, the cover can rotate as a fan along with the holder, a big isolating distance to satisfy the demand of isolator switch, the cover can be removed from the base easily, so it’s easy to install and change the fuse-link. 2 mounting holes on the base, to satisfy the demand of all kinds of switchgear and panels. Two sides of the switch, can install assistant contact, and dispatch the pilot switch close and open state signal. |
