ACREL AKH-0.66 P-50ii Protection Current Transformer

The ACREL AKH-0.66 P-50ii Protection Current Transformer is designed to collect current signals in low-voltage protection systems. The transformer can be used with protection relays and motor protection equipment to provide the current signal required for detecting abnormal current conditions.

For the P-50II model, Acrel specifies rated current ratios from 250 to 600 A with a 5 A or 1 A secondary, a 10P10 accuracy class and a 2.5 VA rated burden. The transformer has an 87 x 113 x 45 mm overall size and a 52 x 32 mm through opening.

How it works

• The primary conductor passes through the current transformer's opening.
• The transformer converts the primary current into a corresponding secondary current signal.
• The secondary signal can be connected to suitable protection equipment for current detection and protection functions.
• The P-50II configuration is intended for protection applications rather than general-purpose current measurement.

Why choose this product

• Designed specifically for low-voltage protection applications.
• Supports several rated current ratios from 250 to 600 A.
• Provides a 10P10 protection accuracy class.
• Compact 50-series construction with a 52 x 32 mm through opening.
• Suitable for integration with protection relays and motor protection equipment where the specified secondary configuration is appropriate.

Benefits

• Provides an isolated current signal for protection equipment.
• Supports overload and short-circuit current detection.
• Offers a defined protection accuracy class for protection circuit applications.
• The through-opening design allows the primary conductor to pass through the transformer without requiring the transformer to form part of the primary circuit.
