KATKO

63-125A Switch Disconnectors

Katko 63-125A switch disconnectors are DIN-rail or screw mounted (KU).

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 (load break switches) and LK12 (change-over switches)

Shafts L=100/200/300 AD11 and L=100/200/300 AD11/VT (load break switches) and L=100/200/300 AD12/VT (change-over switches).

 

Tested according to IEC 60947-3

Available with CCC certificate, mention when ordering

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