ACREL AKH-0.66 P-40II Protection Current Transformer

The ACREL AKH-0.66 P-40II Protection Current Transformer is part of the AKH-0.66/P protection current transformer series. The series is designed to collect low voltage overload and short circuit signals for use with protection relays and motor protection devices. Acrel specifies the series for low voltage distribution protection systems.

The P-40II model is specified with a primary current ratio range of 250 to 400 ampere and a secondary output of 5 ampere or 1 ampere. It has a 10P10 accuracy class and a rated burden of 2.5 VA.

How it works

• The primary conductor passes through the current transformer.
• The transformer converts the primary current into a corresponding secondary current signal.
• The secondary signal can be used by compatible protection equipment to monitor electrical current and identify abnormal current conditions.
• The P-40II is intended for protection applications rather than general-purpose energy metering.
