Project Description


Outdoor Medium Voltage Circuit Breakers

This is an outdoor solution composed of medium voltage circuit breakers enclosed in custom-made casings. This solution is developed in keeping with the most demanding international standards and is able to withstand the most adverse extreme conditions.

Besides the circuit breaker, current transformers are also included, as well as control, measurement, protection and signaling elements.

OCBs are entirely manufactured in welded/bolted steel sheets and fi nished with highly resistant paint.

Optionally, this equipment can be manufactured in stainless steel sheet and fi nished with polyurethane paint.
