MARS 61440 Contactor
The MARS 61440 Contactor is a professional-grade 2 Pole 40 Amp Definite Purpose Contactor built for high-demand residential and commercial HVACR applications. Designed with a 24V coil, this large-body component features a 3-pole frame modified for 2-pole operation, providing superior structural integrity and heat dissipation. It is engineered to handle Full Load Amps (FLA) of 40 and Resistive Amps up to 50, making it a reliable choice for air conditioning, electric heating, and refrigeration systems. The MARS 780 series construction includes high-performance copper and brass conductors to minimize resistance and ensure a cooler-running unit. This model features box lug terminations and an oversized arch window for streamlined wiring, alongside a recessed push-to-test button for rapid field diagnostics. Its universal mounting base allows for seamless replacement of common brands like Siemens/Furnas, Cutler-Hammer, and Square D.
Key Benefits
- Large-Body Durability: Utilizes a 3-pole body configuration to increase life expectancy in taxing thermal environments.
- Enhanced Conductivity: Featured silver cadmium oxide contacts and heavy-duty conductors prevent pitting and maintain maximum current carrying capacity.
- Versatile Wiring: Equipped with multi-purpose coil terminals that accept both QC terminals and stripped wires, plus a removable cover for full contact access.
- Contamination Resistance: The enclosed body design protects the internal mechanism from dust, debris, and insect intrusion, reducing intermittent failures.
- Field Serviceable: Includes removable coils, allowing technicians to replace damaged coils without discarding the entire assembly.
Common Questions
Can I use the MARS 61440 to replace a 30A contactor?
Yes, you can typically upgrade from a 30A to a 40A definite purpose contactor as long as the coil voltage (24V) and number of poles match. Increasing the amp rating provides a higher safety margin for the load.
Will this work for a 208/230V motor if the coil is 24V?
Yes. The 24V rating refers only to the control circuit (coil) that closes the contacts. The contacts themselves are rated to switch higher line voltages, typically up to 600VAC, covering standard 208/230V residential and commercial equipment.
What is the difference between FLA and LRA on this part?
The 40A Full Load Amps (FLA) is the continuous current the contactor can handle while the motor is running. The Locked Rotor Amps (LRA), often rated much higher, is the brief surge current the contacts can withstand during motor startup.
