The circuit breaker adopts a three-phase pillar structure, featuring stable and reliable breaking performance, no risk of combustion or explosion, no need for maintenance, small size, light weight, and long service life.
The circuit breaker can be equipped with two-phase or three-phase current transformers for overcurrent or short-circuit protection, and it can also provide current collection signals for the intelligent controller. According to user requirements, metering current transformers can be added.
The circuit breaker can be equipped with a three-phase interlocking disconnect switch. When the disconnect switch is in the open position, there is a clearly visible break. It also has an anti-misoperation interlock device between the circuit breaker body and the disconnect switch. The circuit breaker can only be operated when the disconnect switch is fully closed or fully opened. It can also be connected with a lightning arrester support insulator, making maintenance convenient.
