GYM9-DC DC Circuit Breaker

GYM9-DC DC circuit breaker is used for DC voltage to 1000V, rated current to 63A line, for overload and short-circuit protection, and also for line's infrequent operation conversion. Circuit breakers are suitable for DC applications such as communication and photovoltaic systems.

* Short-circuit protection
* Overload protection
* Close quickly
* high breaking capacity
* Isolation function
* Indication function of contact position
* Transparent cover designed to carry label.
* Support 35mm Din – rail installation
* Support top incoming and bottom outgoing wiring type, or bottom incoming and top outgoing wiring type.
* Able to select electrical accessories and achieve distant indication of MCB condition: breaking, closed, and fault tripping.
* Able to select electrical accessories and realize under-voltage and over-voltage protection of MCB and distant shunt release.
