12kV Indoor Disconnect Switch GN19

The GN19-12 series indoor isolating switch is designed for 12kV systems and is suitable for use in substations and high-voltage switchgear assemblies. Featuring a three-phase knife-type structure, the unit ensures stable, long-term operation in indoor high-voltage power distribution environments. This switch is intended solely for isolation purposes; it must not be operated under load and requires use in conjunction with a circuit breaker. Isolation is performed only after the circuit has been de-energized, providing a safe, visible break that effectively prevents accidental re-energization and ensures safety during maintenance. The switch can be equipped with the CS6-1 manual operating mechanism, offering ease of operation and reliable performance. A range of rated current options is available.
