KATKO
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.
Â
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).
Â
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.
LOCC-Box from Lutze is an intelligent current monitoring device that provides reliable protection of DC circuits in a slimline 8.1mm housing.
