REV-3POL-37kW B/G

Revision switch (black/grey) made of UV and weather-resistant plastic.

Can be locked in the "Off" position via padlocks.

3 poles + 1 auxiliary contact (1x NO contact).

When operating with explosion-proof fans, the switch must be installed outside the explosive atmosphere.

Note: 

In combination with units of the Topvex series, the switch must be used as a service switch. This means that the AHU must be shut down and off via the control system, 

before the switch is operated.
