The MARS 61460 Contactor is a professional-grade 3 pole definite purpose contactor engineered for consistent performance in demanding commercial HVACR and industrial motor control applications. With an inductive current rating of 50A and a resistive rating of 63A, this component is built to manage heavy electrical loads in refrigeration systems, air conditioning units, and electric heating arrays. The 24V coil is designed for low-voltage control circuits, while the enclosed body design minimizes noise and prevents the intrusion of dust, dirt, and insects, ensuring a longer service life in the field. This MARS 780 series model features high-performance silver cadmium oxide contacts and brass-to-copper electrical paths, which significantly reduce resistance and operating temperatures compared to standard steel alternatives. For simplified installation, the contactor includes box lug termination with oversized "Arch Windows" for easier wiring and multi-purpose coil terminals for quick-connect or stripped wire configurations. It is footprint compatible with many existing 50 amp contactor setups, including those from Furnas, and supports the addition of auxiliary switches via side attachment rails for expanded functionality on the job site. Key Benefits for Technicians Silver Cadmium Oxide Contacts: Provides superior durability when switching inductive loads like compressors and fan motors. Enclosed Body Construction: Reduces operational noise and protects internal electrical components from environmental contaminants. High-Capacity 50A Rating: Reliable power handling for 3-phase HVAC systems and large-scale refrigeration equipment. Universal Compatibility: Industry-standard mounting and support for MARS 780 auxiliary switches simplify field replacements. Box Lug Terminals: Secure, high-current connections designed to handle up to 3-25 HP motor loads depending on line voltage. Common Questions & Answers Can I use the MARS 61460 to replace a Furnas contactor? Yes. This MARS 61460 is a professional-grade drop-in replacement for equivalent Furnas 3 pole 50A contactors, maintaining the same footprint and performance specs. Does this contactor support auxiliary switches? Yes, it features side attachment rails that allow for the installation of standard MARS 780 or Furnas auxiliary switches to provide additional signaling or control loops. What is the benefit of the enclosed body on this 50 amp contactor? The enclosed design prevents common failures caused by arcing due to debris or insect intrusion, while also dampening the mechanical "chatter" during operation.
