HVAC Contactor 120 VAC 30 Amp

The Emerson Climate Technologies 90-245 is a two-pole mechanical contactor built for heating and air conditioning equipment. It operates on a 120 VAC coil and handles 30 Amp resistive loads. A low VA coil design promotes cooler running temperatures and extended service life. Universal mounting brackets align with existing holes for straightforward replacement.

Suits standard AC and furnace replacements

This contactor fits residential and light commercial units requiring a two-pole switch with a 120 VAC coil. Technicians servicing equipment with matching electrical ratings will find the screw terminals and dual quick-connects familiar. Installers needing three-pole switching, a different coil voltage, or higher amperage ratings must select a different model. The definite purpose design is not intended for general lighting or motor control applications beyond its rating.

Low VA coil runs cooler for longer life

The reduced coil volt-ampere draw lowers internal heat generation during continuous operation. Cooler winding temperatures directly contribute to increased contactor lifespan and reliable pull-in performance. Quiet operation results from the efficient electromagnetic design. This single specification distinguishes the 90-245 from standard-duty alternatives that run hotter under the same load.
