Industrial TMX340B2 Definite Purpose Contactor

The Titan Max TMX340B2 Definite Purpose Contactor is a 3‑pole, AC‑coil device designed to switch high‑current loads in HVAC and industrial motor control systems from a 110/120 VAC control circuit. It delivers 40 A full‑load (50 A resistive) with heavy‑duty power contacts and a universal metal mounting plate, suitable for residential, commercial, and light industrial HVAC equipment such as condensers, heat pumps, rooftop units, and refrigeration systems. With an electrical life of 250,000 cycles and a mechanical life of 1,000,000 cycles, it is commonly used to control compressors and condenser fan motors in OEM panels and service applications. Common replacements include Packard C340B, Eaton C25DNF340B, and MARS 61757.
