MARS 92340 Relay

The MARS 92340 Relay is a heavy-duty DPDT 24V relay designed for demanding switching applications in residential and commercial HVAC units. Engineered as a non-positional switching solution, this 24V coil relay features a Double Pole Double Throw configuration, allowing for the simultaneous control of two independent circuits. With a robust resistive contact rating of 25 Amps at 277 VAC and an inductive rating of 15 Amps, it is the industry standard for managing fan motors, heating elements, and refrigeration compressors where reliability is non-negotiable. The MARS 92340 provides a universal fit with its tab mounting bracket and 1/4-inch quick-connect terminals, making it a drop-in replacement for common Essex/RBM 184 series and Honeywell R8222D models. Its compact footprint ensures it fits into tight control panels while providing superior arc resistance and high-load stability for furnace fan control and multi-stage air conditioning systems.

• Universal Field Replacement: Replaces cross-references for Essex/RBM 90-340 and Honeywell R8222D1014, reducing van stock requirements.
• High Current Capacity: Rated for 25A resistive and 15A inductive at 277 VAC, ensuring durability under high-load motor starting conditions.
• A2L Refrigerant Compliant: Suitable for use in newer HVAC systems utilizing mildly flammable A2L refrigerants.
• Flexible Installation: Professional-grade quick-connect terminals and a universal mounting bracket allow for rapid, secure wiring.

Is the MARS 92340 a direct replacement for the Honeywell R8222 series?
Yes, the 92340 is specifically designed to replace the Honeywell R8222D1014 and RBM 90-340 models, making it the preferred choice for universal HVAC repairs.

What is the difference between DPDT and SPDT for this relay?
This DPDT relay features two poles and two throws, meaning it can switch or isolate two separate circuits simultaneously, whereas an SPDT version only manages one circuit.

Can I use this relay for both heating and cooling applications?
Absolutely. The 24V coil and high-amperage contacts are built for fan center switching in furnaces, heat pumps, and air conditioning condensers.
