RB-Series Resistors
Danotherm RB-Series resistors are designed for applications where compact size, high reliability, and exceptional pulse-load capability are critical. Featuring a rugged wirewound element housed in a gold-anodised aluminium enclosure with integrated cooling fins, the RB-Series delivers outstanding heat dissipation and long-term performance in demanding industrial environments.

RB-SERIES RESISTORS
Compact, Pulse-Resilient Performance for Heavy-Duty Industrial Applications
Optimised for both continuous loads and repetitive pulse duty, RB-Series resistors utilise a ceramic or steatite core with precision copper-nickel or nickel-chrome winding, providing excellent thermal conductivity and electrical stability. When correctly mounted to a heatsink, power ratings range from 12 W to 250 W, with operating voltages up to 2,300 VAC depending on the model.

RB-SERIES RESISTORS
Built for High-Pulse Applications
The RB-Series is specifically engineered to withstand repeated pulse loads and short-term overload conditions. Properly heatsinked units can safely absorb significant surge energy and sustain up to five times their nominal power for short durations, making them an ideal choice for heavy-duty control systems and power management applications.
