Vacuum Circuit Breaker MVS13-12 (ZN28)

Solutions

 

Appearance of the switch of the MVS13-12 series

Note: the drive mechanism is in a dotted frame;

No. 17 (insulating partition) is not necessary; the distance between centers is 230 mm or 250 mm (if the distance between centers is 210 mm, see size in brackets).
