KATKO

100-160A Switch Disconnectors

Katko 100-160A switch disconnectors are din rail/screw mountable(KU) and are a modular design.

3-pole and 4-pole KU-switches as standard. Other configurations on request.

6-pole and 8-pole versions consist of two 3-pole or 4-pole KU-switches connected by a parallel kit.

 

Switch technology by means of silver contacts ensures safe and durable operation. Compatible with handles LK10 and LK11 (3 and 4 poles) and LK12 (6 and 8 poles) and LK12CO102 (change-over switch). Shafts L=100/200/300 AD11 and L=100/200/300 AD11/VT (3 and 4 poles), L=100/200/300 AD12/VT (6 and 8 poles and change-over switch).

 

Note! Al-cables cannot be connected directly to switch terminals. For Al-cable connection please use a bi-metal cable connector.
