Introduce
The HPR Series Low-Voltage Protection Current Transformers are specifically designed for multi-busbar relay protection circuits and are widely utilized in low-voltage power distribution protection systems. These products effectively detect short-circuit faults and, when used in conjunction with protective relays or motor protection units, ensure the safe and stable operation of the power system.
Features
- High Precision, Large Capacity: Supports accuracy classes 0.5 and 1.0, with a burden range of 1.5 VA to 30 VA, meeting diverse protection requirements.
- Multiple Transformation Ratio Options: The primary current range covers 100 A to 8000 A, with secondary output options of 1 A or 5 A.
- Excellent Electrical Performance: Rated voltage of 0.72 kV, operating frequency of 50 Hz–60 Hz, featuring high thermal and dynamic stability.
- Innovative Structure, Convenient Installation: Supports DIN rail or busbar mounting, adapting to various installation environments.
- High-Quality Materials: The housing is constructed from imported flame-retardant polycarbonate (PC) capable of withstanding temperatures up to 120°C; the core is made of high-grade cold-rolled silicon steel strip, and the secondary coil utilizes high-strength enameled electromagnetic wire.
- Compliance with International Standards: The product design complies with standards such as IEC 61869-2, EN 60044-1, VDE 0414-44-1, and GB 1208-2006.
Application
- Overload and Short-Circuit Signal Acquisition for Low-Voltage Power Distribution Systems
- Designed for use in conjunction with protective relays or motor protection units
