Resideo R8246A1004/B Contactor

The Resideo R8246A1004/B Quiet Electric Heat Contactor is a veterans choice for reliable 2-pole DPST switching in residential and light commercial electric heating systems. Engineered specifically for 24V HVAC control, this contactor is the industry-standard solution for replacing over 50 competitive primaries, including the legacy R8330 Furnace Sequencer. Its specialized quiet operation design eliminates the loud mechanical "thump" typical of standard contactors, providing a seamless startup that prevents cold drafts and increases occupant comfort.

This DPST electric heat contactor is built for durability with a 60-amp resistive load capacity per pole at 240/277VAC and handles up to 48 amperes for NEC circuit subdivision compliance. The R8246A1004/B features flexible No. 10 terminal clamp screws and male 1/4-inch double quick-connects, ensuring secure, vibration-resistant 24 VAC coil connections. Whether you are servicing an electric furnace or a baseboard heating array, this component provides the fast, dependable ON/OFF switching required for modern low voltage heat primaries.

Key Benefits for Technicians:

• Universal Replacement: Drops directly into place for various legacy relays and sequencers, drastically reducing the need for truck stock.
• High-Amp Capacity: Rated for up to 60A resistive loads, making it suitable for multi-element electric furnace applications.
• Enhanced Coil Connectivity: Equipped with dual-style terminals (clamp screw and quick-connect) to fit any existing wiring configuration.
• Efficient Thermal Control: Precise switching prevents rapid cycling and ensures consistent 240V element engagement.
• Resistant Build: Compact footprint (approx. 3.3" x 2.3") fits easily into tight control cabinets and blower compartments.

Common Questions:

Can this replace a single-pole sequencer?
Yes, the 2-pole DPST configuration of the Resideo R8246A1004/B allows it to replace single-pole units while providing additional switching capacity for heating elements and blowers.

Is this compatible with pilot duty limits?
Absolutely. It is designed to work with both line voltage and pilot duty limits, ensuring compatibility with various safety circuit designs.

What is the coil current draw?
The contactor maintains a constant 0.23 amp draw on the 24V transformer, allowing for stable performance without overloading the control circuit.
