MARS 61432 Contactor

The MARS 61432 Contactor is a professional-grade 3-pole definite purpose contactor engineered for heavy-duty HVACR applications. Designed with a 240V coil and a 30A inductive load rating (40A resistive), this component is a standard for controlling compressors, fan motors, and electric heating circuits in residential and commercial equipment. The enclosed body design protects internal components from dust, debris, and insects, significantly reducing common failure points in the field.

For technicians and contractors, the MARS 61432 features silver cadmium oxide contacts to provide long-lasting conductivity and high resistance to electrical arcing. The unit includes screw type terminations and large arch window box lugs for secure wiring. This model is footprint compatible with many existing 30-amp 3-pole setups and is designed to accept MARS 780 auxiliary switches, allowing for flexible field configurations and reliable switching across 50/60 Hz frequencies.

Key Benefits for Field Installations

• High-Durability Contacts: Silver cadmium oxide contacts minimize pitting and extend the operational life under high inductive loads.
• Contamination Protection: The enclosed body design ensures quiet operation and prevents mechanical failure caused by environmental debris.
• Universal Compatibility: Standard mounting footprint facilitates fast replacement in systems requiring a 3-pole 30A contactor.
• Diagnostic Convenience: Features a recessed push-to-test button to quickly verify circuit continuity without a multimeter during troubleshooting.
• Secure Termination: Equipped with SEMS screws and large box lugs to ensure tight, vibration-resistant electrical connections.

Common Technical Questions

Can I use this for a 3-phase motor application?
Yes, as a 3-pole contactor, the MARS 61432 is designed to switch all three legs of a 3-phase power supply, provided the motor does not exceed the 30-amp inductive rating.

Is the coil compatible with 208V systems?
Correct. The coil is rated for a range of 208-240 VAC, making it suitable for standard commercial and residential voltages.

Will this accept auxiliary switches for feedback loops?
Yes, it is designed with side attachment rails that accept MARS 780 and Furnas auxiliary switches for additional control logic requirements.
