Resideo R8246A1038 Contactor

The Resideo R8246A1038 Contactor is a heavy-duty 2-pole electrical heat primary designed for direct on-off control of heating elements and blower motors in electric furnaces. For technicians working on retrofits, this unit is the direct replacement for R8246A1046 and serves as a versatile substitute for over 50 competitive models, including the R8330 Electric Furnace Sequencer. It features a 24VAC coil rating and a robust 48 amp resistive contact rating at 240/277 VAC, providing the current-carrying capacity required for high-demand residential and commercial heating cycles. Installation is streamlined with No. 10 terminal clamp screws and double male 1/4" quick-connects, ensuring secure wire termination in tight furnace vestibules. Engineered for quiet operation, this contactor eliminates the audible chatter often found in worn-out relays, maintaining system efficiency across a wide ambient temperature range of -4°F to +149°F.

• Universal Application: Simplifies truck stock by replacing various furnace sequencers and electric heat primaries.
• High Current Capacity: The 48A resistive rating allows for reliable switching of high-wattage heating banks.
• Flexible Wiring: Features multiple connection points, including terminal clamp screws and 1/4 inch quick connects for flexible field mounting.
• Eliminates Cold Drafts: Rapid on-off switching logic ensures fan and element synchronization for consistent discharge air temperatures.
• Compact Footprint: 2-3/16 inch height allows for easy fitment in standard control boxes.
