MARS 61481 Contactor
The MARS 61481 Contactor is a professional-grade 3-pole definite purpose contactor engineered for high-demand HVACR and industrial applications. Designed with a robust frame, this 75 amp contactor handles 75 FLA inductive and 94A non-inductive loads, making it a reliable choice for large-scale air conditioning, commercial refrigeration, and electric heating systems. Equipped with a 120V coil and class F insulation, this unit ensures stable switching in environments up to 600VAC. The enclosed body design minimizes dust and debris intrusion, which reduces mechanical wear and ensures quiet operation in sensitive installations.
Built for efficiency in the field, the MARS 61481 features box lug terminals with dual quick-connect coil terminals to facilitate fast and secure wiring. The silver-cadmium oxide contacts are specifically designed to provide superior conductivity and prevent welding during high-amperage cycles. This contactor is footprint-compatible with standard industrial mounts and interfaces seamlessly with HVAC replacement components for quick system recovery.
Key Benefits:
- High Amperage Capacity: Rated for 75 FLA (Full Load Amps) and up to 450 LRA at 240V, suitable for heavy-duty motor starts.
- Durable Construction: Features an enclosed housing to protect internal components and prolong service life in harsh conditions.
- Broad Compatibility: Accepts standard MARS 780 and Furnas auxiliary switches for expanded control circuit functionality.
- Secure Termination: Large arch window box lugs accommodate high-gauge wiring for maximum torque and connection stability.
Common Questions:
What is the difference between FLA and resistive ratings on this 75A contactor?
The 75A rating refers to Full Load Amps (FLA) for inductive loads like compressors or motors. For resistive loads, such as electric heating elements, the MARS 61481 is rated for 94A.
Can I use this 3-pole contactor for single-phase systems?
While designed for 3-phase applications, it can be used for single-phase equipment; however, standard practice typically suggests matching the pole count to the line legs being switched for optimal efficiency.
Does this unit include a manual push-to-test button?
No, the MARS 61481 (75A and 90A models) usually does not feature a recessed push-to-test button, as these larger frames prioritize terminal security and enclosed safety.
