ACREL AKH-0.66 P-170 x 100ii Protection Current Transformer
ACREL AKH-0.66 P-170 x 100ii Protection Current Transformer is a protection current transformer for low voltage relay protection applications. It is designed for circuits where multiple busbars pass through the transformer and is available with rated current ratios from 1000/5 A to 5000/5 A. The model has a 172 x 105 mm through opening and supports 5P protection accuracy classes, making it suitable for protection systems requiring current detection during abnormal operating conditions.
The ACREL AKH-0.66 P-170 x 100ii Protection Current Transformer is part of the AKH-0.66/P protection current transformer range. It is designed primarily for relay protection circuits with multiple busbars passing through the transformer.
The transformer provides a secondary current output for connection to compatible protection equipment. The P-170 x 100II configuration supports several rated current ratios and protection accuracy options, allowing the CT to be selected according to the requirements of the protection circuit.
How it works
- The primary conductor or busbar passes through the CT opening.
- The transformer senses the primary current and produces a proportional secondary current.
- The secondary signal can be used by compatible protection equipment to monitor current conditions.
- The protection characteristics vary according to the selected rated current ratio and accuracy class.
Why choose this product
- Designed specifically for relay protection applications.
- Large 172 x 105 mm through opening accommodates the specified busbar arrangements.
- Multiple current ratio options are available for the P-170 x 100II configuration.
- Provides 5P protection accuracy options specified by the manufacturer.
- Suitable for low voltage distribution protection systems.
Benefits
- Supports current-based protection functions.
- Allows selection of the CT ratio according to the protection circuit.
- Suitable for applications involving multiple busbars.
- Provides a dedicated CT configuration for protection rather than general current measurement.
