ACREL 220 x 50ii Current Transformer for Electrical Monitoring

The ACREL 220 x 50ii Current Transformer for Electrical Monitoring is part of the AKH 0.66 II series of measuring current transformers. The horizontal square hole construction is designed to allow busbars or multiple cables to pass through the transformer without requiring the conductor to be disconnected for installation.

For the 220 x 50 II configuration, the manufacturer specifies an overall size of 280 millimetres by 190 millimetres by 60 millimetres and a through size of 225 millimetres by 55 millimetres. The mounting dimensions include a mounting size of 65, 55 and 65 millimetres and a mounting dimension of 83 millimetres, according to the manufacturer's dimensional drawing.

How it works

• The primary conductor passes through the transformer opening.
• The current transformer converts the primary current into a proportional secondary current for connection to suitable measuring equipment.
• The 220 x 50 II configuration provides a large through opening for suitable busbar and cable arrangements.
• The manufacturer specifies one straight through turn for the listed high current configurations.

Why choose this product

• Designed specifically for high current electrical measurement.
• Large through opening accommodates suitable busbar or multiple cable installations.
• Available with primary current ratios from 1500 to 5000 amperes according to the manufacturer's documentation.
• Suitable for use with electrical measuring instruments and electrical equipment.
• The manufacturer provides dimensional and installation information for the 220 x 50 II configuration.

Benefits

• Supports current measurement in high current electrical systems.
• Allows installation around suitable existing conductors.
• Provides a defined secondary current for compatible measurement equipment.
• The horizontal square construction can accommodate larger conductor arrangements than smaller current transformer apertures.
