ACREL AKH-0.66 P-100iii Protection Current Transformer
ACREL AKH-0.66 P-100iii Protection Current Transformer is a protection current transformer for low-voltage power distribution and relay protection applications. It is designed for installation around 100 mm x 10 mm busbars and is available with multiple primary current ratios from 600/5 A to 3000/5 A. The transformer provides protection accuracy options including 5P5, 5P10 and 5P15, depending on the selected current ratio.
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.
