Motorized isolator switch

rotarymanualmedium-voltage

Product overview
No-load switches act as disconnectors, change-over switches and earthing switches for traction circuits. Units can combine functions in a single modular multipole assembly. They may be fitted with locking systems for safety procedures and mounted in underframe boxes, on vehicle roofs or inside vehicle equipment bays. Operation is manual or by electric/pneumatic drive. Standards: IEC 60077-1, IEC 60077-2, EN 50124-1, EN 50163, EN45545-2.
