C350A 3-Pole 50A 24V Definite Purpose Contactor

The Packard C350A is a 3-pole, 50-amp definite purpose contactor with a 24V AC coil, engineered for heavier-duty HVAC and commercial applications that demand more switching capacity than a standard 30-amp unit. With a 50-amp inductive rating and 3-pole configuration, it's purpose-built for larger compressors, commercial air conditioning systems, heat pumps, commercial refrigeration units, and other high-draw three-phase motor loads.
 
Rated for loads up to 600V AC and compatible with both 50 and 60 Hz systems, the C350A delivers reliable performance across a wide range of commercial installations. Class B coil insulation ensures durability through repeated switching cycles and elevated operating temperatures, while the 24V coil makes it compatible with standard low-voltage thermostat control circuits. It comes ready to install with lugs, spade terminals, and covers included.
UL listed and meeting the ARI 780/790 standard, the C350A is a proven drop-in replacement for comparable units from Cutler-Hammer, Siemens, Mars, Supco, Hartland Controls, and Smart Electric — making it a reliable go-to for commercial service and repair work.
