Detuned reactors, 525V, 3INPP7

Product catalog summary

Standards and Compliance:
The document outlines compliance with several standards including IEC60289, IEC60076, VDE 0532, UL/Ur file E202612, RoHs, and CE. These standards ensure the product meets international safety, environmental, and performance criteria.

Design Specifications:
The reactor series features an iron core with multiple air gaps and uses low-loss grain-oriented steel. It is designed for harmonic filtering with high-quality materials, optimized to reduce total losses, and has a small mechanical size. The design also ensures a low noise level due to glued air gaps.

Technical Specifications:
- Inductance tolerance is -3/+3%.
- Linearity is maintained at 95% inductance at 1.75 times the nominal current.
- Insulation level is rated at 4 kVac.
- Temperature classes are F (155°C) for 6.25-12.5 kvar and H (180°C) for 25-75 kvar.
- Cooling is achieved naturally, and the ambient temperature range is -20 to +60°C (T60).
- Protection class is IP00, and installation is via screw fastening.
- The noise level is a maximum of 50 dB at a 1-meter distance with rated harmonic currents.

Optional Features:
- Temperature switch ranging from 130-150°C with a tolerance of ±5%, suitable for 250 Vac (<6.3A) to 500 Vac (<2A).
- Stranded wire outputs with flexible cable rated at 110°C.
- Lateral mounting options are available.

Performance Data:
The document provides detailed performance data for various kvar ratings (6.25, 12.5, 25, 50, 75, 100 kvar) including filtering factor, inductance, current ratings, linearity, losses, and weight. The reactors are designed for use with rated capacitors and are part of the 525V series, type 3INPP7.

Mechanical and Connection Details:
Mechanical dimensions and connection details are provided for different kvar ratings. The reactors use screw terminals or busbars for connections, with specified clamp sizes and tightening torques.

Packing and Ordering Information:
The document includes packing details and order codes for reactors with and without temperature switches, along with their respective dimensions and weights.
