PWNS 2/6 - indoor switch with motor drive
The switch is designed for switching electrical circuits without the load. It is a three-pole device used in medium voltage switchgears for switching on, switching or grounding electrical circuits. Switching operations are performed by a motor drive mounted on the device. Device's positioning is done by auxiliary contacts (at least 2NO + 2NC).
- high short-circuit current
- contacts covered with silver
- high strength
- small dimensions
The indoor PWNS motor-driven switch has a secant design. The current path consists of three fixed contacts and a movable contact and is attached to four plate-shaped post insulators. The movable contacts are fastened with the drive shafts. The device is maneuvered by electric or manual drive. The entire contact system is covered with silver, which facilitates the flow of short-circuit currents.
