The TE2500B3R9J is a high-power, wire-wound tubular resistor from the TE Series, designed for stability and reliability in heavy-duty applications. It features a mullite-coated ceramic core with a corrugated ribbon element that facilitates rapid cooling, enabling a power handling capability of 2500W in free air. This resistor has a resistance value of 3.9 Ohms with a tolerance of ±5% and operates across a temperature range of -25°C to +225°C. Its flameproof construction can withstand a 3x overload for 5 seconds, making it a robust choice for demanding environments. Common applications include motor start/stop cycles, load test simulation, capacitor charging and discharging, and equipment discharge in industrial machinery.
