Porcelain Clad Vacuum Circuit Breakers (PCVCB)

BHEEM Series of porcelain clad vacuum circuit breakers are structure mounted, easy to use devices for outdoor applications in 12kV and 36kV systems. They come with well proven vacuum interrupters from Megawin with adequate phase clearances and heights, suited for overhead lines and cables. Bheem series of VCB come with non-parallel performance by incorporating current sensors and voltage sensors on to the terminal pads.

Embedded Current and Voltage Sensors

Current sensors and voltage sensors are a direct replacement to current and potential transformers. When incorporated into Metal clad switchgear it makes your switchgear failure free.

Embedded Current and Voltage Sensors

Current and voltage sensors are designed for both metering and protection, covering all your specification in one design with added benefits.

Protection Class: 5P40
Metering: 0.2s
