Circuit Breaker - EcoBreaker™

The World's First Solid Dielectric Substation Outdoor Circuit Breaker with Full Parallel Redundancy

SF6 Free and Maintenance Free

Advanced heat sink design and innovations in Solid Dielectric heat transfer allows the SCB EcoBreaker™ to bring SF6-free technology to the substation.

Versatile Instrumentation

The SCB EcoBreaker™ has provision for six current transformers per phase and generous marshalling cabinet provisioning for terminal blocks.

Dual Parallel Electronics with ample provision for substation instrumentation connections and terminal blocks.

Safety First

Arc Fault Classification provides clear safety benefits over legacy Live-Tank switchgear design.

Dual-earthed dead tank arrangement provides added safety for operators.

Full Parallel Redundancy

Two trip coils and a close coil for every pole. The reliability-first design requires only 2 of the 6 trip coils to operate to open all phases, providing performance assurance in even the most arduous environments.

Offered in Standard and Full Parallel Redundancy builds, with the latter including an additional fully separate electronic control system.
