Our OTDC switches from 100 to 250 Amperes are the only ones in the market that reach 1000 VDC with only 2 poles.
The new OTDC range includes IEC and UL versions.
- IEC 60947-3 (from 100 to 250 Amperes)
- UL98B listed (from 100 to 200 Amperes)
All available documents for switch-disconnectors
OTDC from 100 to 250 Amperes has the following features:
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.
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
Designed for safety
- Flexibility to use in diverse applications.
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.
