MARS 61474 Contactor

The MARS 61474 is an industrial-grade 3 pole 60 amp contactor engineered for heavy-duty switching in commercial refrigeration, large-scale HVAC units, and electric heating systems. Operating with a 480V coil, this definite purpose contactor is designed to manage high inductive loads from compressors and motors with minimal arcing. The enclosed body construction protects internal silver-cadmium contacts from dust and insect intrusion, ensuring consistent conductivity and a quieter operation during rapid cycling. This model is a reliable replacement for outdated 480V controllers in 3-phase power applications, meeting ARI 780/790 standards for 200,000 electrical life cycles.

Installation is streamlined through the box lug terminals and dual quick-connects, which allow for secure high-gauge wiring and flexible secondary connections. The universal mounting base provides compatibility with various existing bracket configurations, making it a "drop-in" solution for field repairs. With copper and brass conductors, the MARS 61474 maximizes current carrying capacity while maintaining a cooler operating temperature under full 60A FLA (inductive) or 75A resistive loads. For contractors handling 3-phase industrial gear, this component is the professional choice for long-term system reliability.

• Durable Box Lugs: Ensures high-torque wire retention for 3-phase high-current applications.
• Enclosed Coil Housing: Protects against environmental contaminants to prevent premature mechanical failure.
• High-Performance Contacts: Silver-cadmium oxide formulation provides superior arc resistance and cycling longevity.
• Universal Compatibility: Standardized mounting footprint allows for easy replacement of most 60A 3-pole contactors.
• Optimized Heat Dissipation: High-grade copper conductors reduce thermal stress during 480V operation.

• Can this be used for a 3-phase compressor? Yes, the 60A 3 pole configuration is specifically rated for definite purpose inductive motor loads common in industrial HVAC.
• What is the difference between inductive and resistive ratings for this part? It is rated at 60 FLA for inductive loads (motors) and 75A for resistive loads (electric heat).
• Will the 480V coil work with a 277V control circuit? No, this unit requires a dedicated 480V control signal to engage the coil; check your transformer output before installation.
