SWITCH DISCONNECTORS FOR PV APPLICATION

ABB offers a compact DC switch range for single and multi circuit disconnecting
Carefully designed arc plates and dual magnetic breaking, breaking power is optimized across the entire current range.
As a result of symmetric pole design, the connections are independent of polarity. The user can make the connections in both ways.
OTDC is the only DC switch in the market that has visible contacts.
Special four pole versions can be made for double circuit applications
The operation of the switch is not vulnerable to voltage peaks and it is independent of the user (quick make quick brake).
The switches are available in direct mounting handle version as well as external door mounted handle version
The power losses are very low, results in high efficiency.
