MARS 61491 Contactor
The MARS 61491 Contactor is a professional-grade 3-pole definite purpose contactor engineered for high-demand commercial refrigeration, air conditioning, and electric heating systems. Carrying a 90 Amp inductive rating and a 120V coil, this heavy-duty component provides reliable load management for large-scale HVACR equipment. This model serves as the direct replacement for the CON-3/120/90, ensuring a seamless fit and electrical compatibility in existing control panels. Built with an enclosed body, it minimizes dust intrusion and mechanical noise, making it suitable for noise-sensitive installations. The MARS 61491 features high-performance copper and brass conductors that maximize current-carrying capacity while maintaining low operating temperatures to prevent contact pitting. With box lug terminals and a standard foot-print, technicians can execute fast, secure terminations. This 120V 90A contactor utilizes silver-cadmium oxide contacts to increase total cycles under inductive loads, delivering the durability required by service contractors in the field.
Key Benefits- High-Capacity Switching: Rated for 90 Amps FLA and up to 120 Amps resistive, handling heavy electrical loads without overheating.
- Direct CON-3/120/90 Replacement: Designed as an exact cross-reference for the CON-3/120/90 to simplify inventory and onsite repairs.
- Quiet Operation: The enclosed housing design reduces the loud "chatter" or hum often found in open-frame magnetic contactors.
- Simplified Wiring: Features an oversized arch window and box lug terminals to accommodate larger gauge wire and speed up installation.
- Professional Grade Durability: Silver-cadmium oxide contacts resist welding and arc erosion during high-cycle heating and cooling demands.
Is the MARS 61491 compatible with auxiliary switches?
While smaller 780 series units accept side-mounted auxiliary switches, the 90A large-frame MARS 61491 is typically used as a standalone power switch. Verify your specific footprint and mounting rail requirements if adding external interlocks.
Can I use this to replace a 2-pole 90A contactor?
Yes, a 3-pole contactor can be used in place of a 1-pole or 2-pole unit by utilizing only the required poles, provided the 120V coil voltage and amperage ratings match the system specifications.
What is the maximum voltage rating for the contacts?
The contacts are rated for switching up to 600 VAC, making this 90 Amp DP contactor versatile for both 208/230V and 460V commercial applications, as long as the control circuit provides the required 120V coil power.
