MARS 90360 Relay

The MARS 90360 Relay is a heavy-duty SPST 24V relay engineered for rigorous switching applications in HVACR control systems. Recognized as a core component for modern technicians, this switching relay serves as a reliable interface for fan motors, refrigeration compressors, and heating elements. With a 24VAC coil and a 18 Amp contact rating, it provides the necessary ampacity for inductive motor loads and resistive heating circuits. This unit is a direct non-positional relay replacement for the WR/Essex/RBM type 184 and PR360, featuring a universal tab bracket for flexible mounting and 1/4-inch quick-connect terminals to streamline field wiring. Its UL and CSA listed construction ensures compliance in air conditioning and ventilation applications, including A2L compliant environments where safety and performance are non-negotiable for low-voltage control circuits.

• Broad Compatibility: Seamlessly replaces legacy Essex/RBM type 184 and Honeywell R8222 series models.
• Enhanced Load Capacity: Rated for up to 18A resistive loads, making it ideal for higher-amperage HVAC fan centers.
• Simplified Installation: The non-positional design and universal flange mount eliminate orientation issues in tight control cabinets.
• A2L Compliant: Suitable for use with the latest generation of refrigerants and high-efficiency HVACR equipment.
• Reliable Switching: Features a 20.4V pick-up and 4.8V drop-out voltage for precise control and reduced contact chatter.

Is the MARS 90360 suitable for replacing a DPDT relay?
No, this is a Single Pole Single Throw (SPST) relay. If your current control circuit requires multiple poles for separate circuits, verify your wiring diagram before replacing it with this single-pole unit.

Can this relay be used in refrigeration systems?
Yes, the 90360 is frequently used in refrigeration for fan switching and auxiliary control, provided the amperage and 24V coil requirements match the system specifications.

Do I need a specific orientation for mounting?
This relay is non-positional, meaning it can be mounted in any orientation using the included tab bracket without affecting internal mechanical performance.
