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.

We shine a spotlight on surge protection devices (SPDs), a crucial yet often overlooked component in industrial settings. Every surge of electricity, every fluctuation in voltage, poses a potential threat to your machinery and systems.
Renowned for high-quality cable cutting and crimping tools, Klauke serves electrical contractors, cable jointers, and linemen across a spectrum of sectors
At OEM Automatic, we can supply a series of components for your one project. All under one roof. This case study discusses how we supplied several components for our customer's new electro-pneumatic control box.Â
To promote constant and reliable performance, as well as a longer life of parts in the vehicle, it is important to consider the right cable protector.
We have now added switch disconnectors to our range! Switch disconnectors contribute to the overall functionality and safety of electrical systems.
