TE2500B6R8J is a high power wire wound resistor from the TE Series designed for heavy-duty industrial applications. This resistor features a mullite coated tubular ceramic core with a corrugated ribbon element for rapid cooling, enabling a 2500W power rating with a 6.8O resistance value and ±5% tolerance. It operates over a temperature range of -25°C to +225°C with a temperature coefficient within ±440ppm/°C. The flameproof construction supports 3x overload for 5 seconds and withstands AC 2500V for 1 minute. Common applications include large electrical machinery, load test simulation, motor start/stop cycles, and dynamic braking systems.
