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

Hydrophobic cycloaliphatic epoxy bushing (HCEP)
