WLRD6G Series High Current Oval Edgewound NOTE WLRD6G resistors require significant investment in resistance wire due to high minimum order quantities imposed by our vendors. Before ordering always check with the factory on wire availability. A 5" approx.

Choose from five sizes with up to thirty-one current ratings. The units listed below are direct replacements for General Electric 42D6G1XXX or 42D6G3XXX. Built to perform in rugged environments, they feature corrosion resistant stainless steel insulator supports, solid nickel terminals, and special electroless nickel-plated solid copper terminal supports. The resistance element is made of a stainless steel resistance alloy. Terminals are welded or silver brazed to the oval, spiral edgewound resistance element. Toothed ceramic insulators isolate the resistance element from the center support. Ceramic end bushings insulate the center support from the mountings. Order individual replacement units or entire grids with various mounting configurations. Contact us with your specific needs. S p ec i f i c a t i o n s Electrical Current Rating: Continuous duty as listed below. Wattage Rating: Continuous duty based on a 375°C temperature rise. Working Voltage: Limited to 550 Volts if mounting is grounded. Special higher voltage mounting is available. Resistance Tolerance: ±10%. Materials Terminals/Jumpers: Standard terminals have 5/16 stainless hardware for ring lug connections. Brass tags can be placed at connection points for identification. If necessary, all connections can be made on one side of grid. Fixed tap terminals are also available. Jumpers between resistors are nickel plated solid copper. Mounting: Resistors can be mounted in grid arrays of 1 x 2 to 4 x 4. All resistors in one grid must be of the same length. Frames construction is heavy gauge zinc plated steel. Either “bolt up” or “bolt down” type frames are available. Frames may be grounded if voltage potential is below 550 Volts. Single resistor and vertical mounting is available. Ordering Information Individual resistors can be ordered by part number. Example: WLRD6G3061 is a 0.156 ohm, 90 amp rated part.
