ACREL AKH-0.66 P-100iii Protection Current Transformer

The ACREL AKH-0.66 P-100iii Protection Current Transformer is a protection-type current transformer developed for relay protection circuits in low-voltage electrical distribution systems. It converts high primary current into a lower secondary current suitable for connection to protection equipment.

The P-100III configuration is designed for a 100 mm x 10 mm busbar and uses a single straight-through turn. Depending on the selected primary current ratio, the model provides different protection accuracy classes and rated loads.

How it works

• The primary conductor or busbar passes through the current transformer.
• The transformer senses the current flowing through the primary circuit.
• It produces a corresponding secondary current signal for connection to protection equipment.
• The protection system can use this signal to identify abnormal current conditions such as overloads and short circuits.

Why choose this product

• Designed specifically for relay protection applications.
• Suitable for low-voltage power distribution circuits.
• P-100III configuration accommodates a 100 mm x 10 mm busbar.
• Multiple primary current ratios are available within the P-100III range.
• Protection accuracy and rated load can be selected according to the required current ratio.

Benefits

• Provides current sensing for electrical protection systems.
• Supports protection equipment requiring a 5 A secondary current.
• Allows the transformer to be selected according to the primary current of the monitored circuit.
• The busbar-mounted design is suitable for fixed electrical distribution installations.
