Safe and reliable

OTDC from 16…32 Amperes have numerous DC ratings within the same footprint space and the rated operational voltage can be scaled up to 1000 V to suit your application. Tunnel terminals capture fine stranded wires and they are wide enough to allow wires up to 16 mm and short circuit bars are preinstalled as standard.

OTDC switches from 100…250 Amperes are the only 2-pole solution in the market with an operational voltage of 1000 VDC. This is possible thanks to carefully optimized arc plates and dual magnetic breaking.The switches are symmetrical in design and connections are independent of polarity, meaning they can work in both ways.

This isolator switch ensures safe and effective disconnection of electrical circuits. With a maximum current rating of 32A and a voltage capacity of 660V DC, it operates efficiently in various industrial settings. Its compact size is suitable for constrained spaces, while its robust construction meets high-performance requirements.
