Breaker Protection

Hitachi Energy's range of breakers runs from the compact to the comprehensive, offering protection in flexible form factors suited to every application.

Protection goes beyond generators and motors to encompass feeders, transformers, and capacitor banks to name a few. Overcurrent and earth-fault protection are available where needed, and breakers can be fitted to standard 19-inch frames or mounted onto a DIN rail as preferred.

Breaker protection REQ650 provides a standalone solution for applications where the integration of the breaker failure protection or automatic reclosing function into the mainline protection IED (Intelligent Electronic Device) is not preferred or suitable. This IED also offers local back-up protection, synchronizing, synchro check, and energizing check functionality to enable well-structured and reliable protection for various applications.
