Window-Type Current Transformers

Available in multiple sizes and shapes to adapt to different applications. They are designed to guarantee safe insulation levels while providing accurate readings and protection for industrial installations.

Window-type Current Transformers (CTs) provide a protected way to reduce the current for metering. Available in multiple sizes and aspects to suit a diverse array of applications. They ensure accurate, low-level outputs with negligible influence on the primary system.

Primarily used within switchgear, which consist of electrical disconnect switches, or circuit breakers designed to control, protect, and isolate electrical equipment. They enable safe de-energization for maintenance and facilitate fault clearing downstream.
