Star Water Systems 127189A Well Pump Control Box 1/2 Hp 230V

Product Description

The STAR WATER SYSTEMS 127189A is a quick-disconnect pump control box designed for 3-wire, 230-volt submersible well pump installations. Rated for use with 1/2 HP, 3/4 HP, and 1 HP submersible pumps, this control box consolidates all electrical components in an above-ground enclosure, keeping them accessible without pulling the pump. The snap-out cover allows fast access for inspection, troubleshooting, and component replacement. A separate 1-1/2 HP standard disconnect configuration is also supported. The unit weighs 0.285 pounds and is sold individually.

This control box is used in residential well water systems where a 3-wire submersible pump requires above-ground motor starting and protection components. It is suited for new installations and retrofit applications where quick-disconnect access is needed to reduce service time. Keeping all components above grade eliminates the need to pull the pump for routine electrical diagnosis, making it a practical choice for well service contractors and plumbers working on residential water supply systems.
