- Some users note lack of overload relay compared to more expensive models
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.

Buying Guide: What to Look for in a Pump Controller for Submersible Pumps
Motor Compatibility and Voltage
Your pump controller must match your motor’s horsepower and voltage. The Red Lion RLCB10-230 is designed for 1 HP, 230 Volt, 3-wire single-phase submersible pumps. Always verify your pump’s specifications before purchasing. Using an incompatible controller can cause motor failure or inefficiency.
For pumps advertised as 2-wire, no control box is needed. Many Red Lion deep well submersibles come with a control box included, so check the pump description before ordering separately. This ensures you get the right components for your system.
Enclosure Rating and Weather Resistance
If your control box will be installed outdoors, look for a NEMA 3 rating. The Red Lion RLCB10-230 carries this rating, meaning it is rainproof, sleet-resistant, and ice-resistant. It also includes a drain hole and multiple knockouts for conduit connections, making it suitable for various environments.
Indoor installation is also fine, but the weatherproof design adds flexibility. For more on system sizing, see our guide on well pressure tank sizing.
Thermal Protection and Safety Features
A quality pump controller includes built-in thermal protection to prevent overheating. The Red Lion model uses a capacitor start/run design with thermal overload protection. This safeguards the motor during continuous duty cycles, reducing the risk of burnout.
Safety certifications matter too. This control box is UL listed in both the USA and Canada, confirming it meets rigorous safety standards. Always choose controllers with recognized certifications for peace of mind.
Ease of Installation and Maintenance
Look for a controller that simplifies wiring and mounting. The Red Lion RLCB10-230 features heavy-duty box-type terminals and four 7/8-inch knockouts plus three 1-1/8-inch knockouts. Two mounting holes and a drain hole make installation straightforward.

Frequently Asked Questions
What is a pump controller for submersible pumps?
A pump controller, also called a control box, manages the start and stop cycles of a submersible well pump. It houses starting capacitors, relays, and overload protection to ensure safe and efficient operation. The Red Lion RLCB10-230 is a VMC (voltage monitoring control) box designed for 3-wire single-phase pumps.
How do I know if I need a control box for my well pump?
If your submersible pump is a 3-wire model, it requires a separate control box. Two-wire pumps have the starting components built into the motor and do not need an external controller. Check your pump’s documentation or look at the number of wires coming from the motor to determine which type you have.
Can I use the Red Lion RLCB10-230 with any 1 HP submersible pump?
This control box is designed specifically for Red Lion 3-wire single-phase submersible pumps. While it may work with other brands, we recommend using it with compatible Red Lion pumps to ensure proper performance and warranty coverage. Always verify voltage and horsepower ratings before installation.
What maintenance does a pump controller require?
Pump controllers generally require minimal maintenance. Periodically inspect the enclosure for debris or moisture, and check that all electrical connections are tight. As of October 2026, the Red Lion RLCB10-230 remains a top choice with a durable design that reduces the need for frequent service.
