OTDC from 100 to 250 Amperes has the following features:
Optimal design
The design of the arc plates has been carefully optimized for DC applications.
Thanks to dual magnetic breaking, breaking power is balanced for all current levels.
- Breaking power optimized across the entire current range.
As a result of a symmetric design, the connections are independent of polarity. The switch works in both ways.
- Simplicity in installation.
Modularity
The mechanism can be located between the poles or on the side of the switch.
Special four pole versions can be made for double circuit applications.
– 2 poles, 1000 VDC
– 3 poles, 1500 VDC
– 4 poles, 2 × 1000 VDC
- Flexibility to use in diverse applications.
Designed for safety
OTDC is the only DC switch in the market that has visible contacts.
The operation of the switch is not vulnerable to voltage peaks and it is
independent of the user (quick make quick brake).
- Safe and reliable operation.
