OWEL - DC indoor secant disconnector

Application:

OWEL disconnectors are isolating disconnectors designed for closing and opening unloaded circuits in industrial DC current networks. In open position, the disconnector creates visible and safe isolating clearance. It can be installed and operated in closed spaces, in the temperate of - 5°C up to 40°C.

The device does not need spare parts during the time of 1000 cycles, but on special request the spare parts can be delivered to the customer. The replacement should be coordinated with the ELTOM company.

Advantages:

  • simple and modular design
  • reliability
  • silver coated contacts
  • good parameters

Characteristic:

The disconnectors have secant construction. The basis is made of steel and it creates the sub-assembly with the shaft and the limiters of angle of rotation of the shaft. There are signal insulators mounted in the basis, on which there is the busbar. Interpolar insulation is the air gap. Normally, the drive is mounted on the right side of the disconnector. Disconnector can operate in vertical or horizontal position.

The disconnectors OWEL 3-31 and OWEL 3-25 comply with the standard PN−93/E−06107.
