Unknown RXLG-300W30RJ Trapezoidal Aluminum Case Resistor 300 W Resistance 30 Ω

High‑power wire‑wound braking resistor housed in a trapezoidal aluminum heat‑sink enclosure. Designed for servo drives, VFDs, dynamic braking circuits, load testing, and industrial power applications. The finned aluminum body provides excellent heat dissipation, enabling stable operation at high loads. Technical Specifications Model: RXLG‑300W30RJ Type: Aluminum‑housed wire‑wound power resistor Power Rating: 300 W Resistance: 30 Ω (marked “30RJ”, J‑tolerance = ±5%) Tolerance: ±5% (J code) Construction: Trapezoidal finned aluminum heat‑sink case Cooling: Natural air cooling (forced air increases performance) Leads: High‑temperature insulated wire leads Mounting: Base‑mount with screw holes (typical for RXLG series) Temperature Coefficient: Low, wire‑wound stability Typical Applications: Dynamic braking for drives, servo motor discharge, industrial power dissipation, load banks, energy absorption circuits Dimensions (approx.): Based on series type and visible size (aluminum extruded body with long rectangular profile) Manufacturer: Not marked (generic RXLG series, commonly produced by Chinese industrial resistor manufacturers) Country of Manufacture: Not labeled (commonly manufactured in China) Please review pictures carefully and let us know if you have any questions!
