ACREL AKH-0.66 P-120 x 50ii Protection Current Transformer

The ACREL AKH-0.66 P-120 x 50ii Protection Current Transformer is designed for low-voltage distribution and relay protection applications. The P-120x50II configuration provides a rectangular through-opening for busbars, making it suitable for installation within electrical distribution equipment where current signals are required for protection functions.

The manufacturer catalogue lists the P-120x50II with primary current ratios ranging from 600 A to 5000 A, depending on the specified configuration. Secondary output can be selected as 5 A or 1 A. The available configurations also specify protection accuracy classes and corresponding rated loads.

How it works

• The primary conductor or busbar passes through the transformer's rectangular opening.
• Current flowing through the primary conductor produces a corresponding secondary current.
• The secondary output can be connected to compatible protection equipment or measuring circuitry.
• The selected current ratio and protection characteristics determine the appropriate secondary signal for the application.

Why choose this product

• Designed specifically for low-voltage protection applications.
• Rectangular through-opening suitable for busbar installation.
• Multiple primary current ratios are available.
• Secondary output configurations include 5 A and 1 A.
• Suitable for relay protection and short-circuit fault current detection applications.

Benefits

• Provides an isolated current signal for compatible protection equipment.
• Allows high primary currents to be monitored through a lower secondary current.
• Supports different protection requirements through available accuracy classes and rated load configurations.
• The rectangular design provides a practical arrangement for busbar-based electrical distribution equipment.
