The Red Lion RLCB10-230 is a VMC control box designed specifically for 1 HP, 230-volt, 3-wire single-phase submersible well pumps. It is an ideal replacement or upgrade for homeowners and professionals maintaining deep well systems. This control box is built to handle continuous duty with a capacitor start/run design and thermal protection.
Standout features include a weather-resistant NEMA 3 rated enclosure that allows for indoor or outdoor installation. The box comes with quick disconnect relay, capacitors, and overloads. Heavy-duty box type terminals and clearly labeled connections make wiring straightforward. Users praise its sturdy construction and easy installation, often noting it as a cost-effective alternative to more expensive brands.
Build quality is robust with a powder-coated stainless steel finish that resists corrosion. The enclosure includes multiple knockouts for conduit entry and a drain hole to prevent moisture buildup. It is UL listed in the USA and Canada, ensuring safety standards are met.
One potential drawback is that this control box does not include overload protection in the traditional sense; some users recommend adding a separate circuit breaker for full protection. Additionally, it is designed primarily for Red Lion pumps, so compatibility with other brands should be verified before purchase.
Overall, the Red Lion RLCB10-230 offers excellent value for those needing a reliable control box for a 1 HP 230V submersible pump. Its durable build, ease of installation, and weatherproof design make it a solid choice for both replacement and new installations.

Buying Guide for Well Pump Relays
Voltage and Horsepower Compatibility
Before purchasing a well pump relay or control box, verify that it matches your pump’s voltage and horsepower. The Red Lion RLCB10-230 is designed for 1 HP, 230-Volt motors, a common specification for many residential deep well submersible pumps. Using the wrong rating can cause premature failure or unsafe operation.
Always check your pump’s nameplate. If you have a 2-wire pump, you do not need a control box, as the relay is built into the motor. For 3-wire pumps, a separate control box like this one is required. For more details on pump types, see our article on quiet well pumps.
NEMA Enclosure Rating
The enclosure rating determines where you can install the control box. The Red Lion RLCB10-230 carries a NEMA 3 rating, meaning it is suitable for indoor and outdoor use, protecting against rain, sleet, and dust. This flexibility is valuable if you need to mount it near the well head or in a damp basement.
If you plan to install it in a harsh environment, a higher rating like NEMA 4X might be needed, but for most residential setups, NEMA 3 is sufficient. For more on installation considerations, read our well pump with soft start guide.
Capacitor Type and Thermal Protection
A well pump relay works with capacitors to start and run the motor. The Red Lion control box uses a capacitor start/run design with thermal protection. This design provides reliable starting torque and prevents overheating, extending the life of your pump. Look for a control box that includes both start and run capacitors for efficient operation.
Thermal protection is a critical safety feature that shuts off the motor if it overheats, preventing damage. The Red Lion unit has this built in, giving you peace of mind. For a complete system, consider a well pump kit with pressure tank.
Build Quality and Ease of Installation
Heavy-duty terminals and a rugged enclosure ensure the control box withstands the elements and electrical loads. The Red Lion RLCB10-230 features box-type terminals that are easy to wire, and multiple knockouts for conduit connections. It also includes a drain hole and mounting holes for secure installation.
Assembled in the USA and UL listed, this unit meets high quality standards. Before buying, confirm your pump is 3-wire and requires a control box. For more buying tips, explore our complete well pump kit for home guide.
Final Thoughts
For a dependable well pump relay solution, the Red Lion RLCB10-230 1-HP 230-Volt VMC Control Box stands out with its robust build, NEMA 3 rating, and integrated thermal protection. It is an excellent choice for homeowners with a 1 HP, 230-Volt submersible pump looking for a straightforward replacement or upgrade. If you need a control box for a different horsepower or voltage, verify compatibility before purchasing, but for this common specification, the Red Lion delivers reliable performance.
Frequently Asked Questions
How does a well pump relay work?
A well pump relay is an electromagnetic switch that controls the flow of electricity to the pump motor. When the pressure switch signals that water is needed, the relay closes, allowing current to flow and start the pump. It also opens when the pressure tank is full, stopping the pump.
Can I replace a well pump relay myself?
Yes, if you have basic electrical skills and the right tools. However, always turn off power at the breaker before working. The Red Lion RLCB10-230 control box is designed for easy wiring with clearly labeled terminals. If you are unsure, consult a professional. For more guidance, see our well pump for dug well article.
What is the difference between a 2-wire and 3-wire well pump?
A 2-wire pump has the relay and capacitors built into the motor, so it does not need a separate control box. A 3-wire pump requires an external control box that houses the relay, start capacitor, and run capacitor. Most submersible pumps are 3-wire, but always check your pump’s specifications.
How often should a well pump relay be replaced?
There is no set interval, but relays can wear out over time due to frequent cycling, voltage surges, or moisture. If your pump starts intermittently, hums without starting, or trips the breaker, the relay may be faulty. In 2026, many homeowners choose to replace the entire control box for a fresh start.
