MARS 60046 Contactor

The MARS 60046 is a professional-grade 2-pole definite purpose contactor designed for rigorous HVACR applications. Engineered with a 120V coil and rated for 40 FLA (Full Load Amps), this component provides reliable switching for compressors, motors, and heating elements. The integrated internal shunt allows for continuous circuit monitoring and simplified wiring in specific control configurations. Built to withstand demanding duty cycles, it features high-quality silver-cadmium oxide contacts to minimize pitting and ensure long-term conductivity under heavy inductive loads. The universal mounting base offers a standardized footprint, making it an ideal drop-in replacement for common field units from GE, Honeywell, and Square D. With box lug terminals and quad quick-connects, this 120V 40A contactor facilitates fast, secure terminations for field technicians.

• High Amperage Capacity: Rated for 40 Amps Inductive (FLA) and 50 Amps Resistive, suitable for high-demand residential and commercial units.
• Simplified Wiring: Features an integrated shunt and quad 1/4-inch quick-connect terminals for flexible field installation.
• Enhanced Durability: Enclosed coil design and thermoplastic housing protect against dust, debris, and insect intrusion to prevent premature failure.
• Broad Compatibility: Standardized mounting holes and 120V AC coil rating ensure seamless integration into existing control circuits.
• Technical Compliance: Meets ARI 780/790 standards for professional refrigeration and air conditioning service.

Can I use the MARS 60046 to replace a contactor without a shunt?
Yes, provided the coil voltage (120V) and amperage ratings match. The shunt provides a continuous path on one pole which is often used for crankcase heaters or transformer power; verify your schematic before installation.

What is the difference between the box lugs and the quick-connect terminals on this model?
The box lugs are designed for the primary high-current power leads (line and load), while the side quick-connects are typically used for the 120V control circuit and auxiliary accessories.

Is this contactor suitable for 208/230V control circuits?
No. This specific model features a 120V coil. Applying 240V to a 120V coil will cause immediate component failure. Always verify your control transformer output before energizing.
