The Contactor, 50A 3-Pole (120V Coil) is an electrical switching component engineered for Mr.Steam CU Commercial Steam Shower Generators running on 480V/3-phase power. Featuring a 120V coil rated for 50/60 Hz operation, this contactor manages the line and load connections that control power delivery to the generator's heating circuit, supporting safe, reliable switching in demanding commercial environments. Its terminals are configured with "L" (line) connections on top and "T" (load) connections on the bottom, each accepting either spade terminals or wire lugs for flexible field installation, while the coil itself connects via spade or screw terminals. This contactor has been tested and approved specifically for Mr.Steam CU Commercial systems, so substituting a generic contactor is not recommended for maintaining safe, consistent performance. As a direct OEM replacement, it restores dependable electrical switching to a generator's power circuit, helping facility operators avoid the downtime and safety risks that come with a failed or mismatched contactor.
