Humeral motor drive NSNr


Rotary motor drive NSNr is a device designed for quick manoeuvring of the traction load break switch. It causes immediate disconnection and shortens the duration of the disconnectable arc. The drive is equipped with a permanent magnet motor and a worm gear. The device is adapted to manual and remote control, and is protected by a separation of power supply voltage.

The drive enables opening and closing of the traction couplings through the sliding movement of the tubular tendon. It is characterized by high mechanical strength. The drive mechanism is located in a cabinet made of aluminum, powder coated. The drive is attached to the traction pole by means of suitable structures, is equipped with a isolation transformer to eliminate the way back to the electric shock current.
