KATKO
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
Â
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).
Â
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.
