Buying Guide: What to Look for in a Franklin Control Box Relay
Choosing the right relay means more than matching a part number. You need to consider compatibility, build quality, amp rating, and how easy it is to install. Here are the key factors we used to assess each product.
Compatibility with Your Franklin Control Box
The most critical factor is ensuring the relay fits your specific model. All six products listed are compatible with Franklin control boxes from 5 to 15 HP at 230 volts. However, the last product (RVAH2ALKL) is a 50A relay that replaces different part numbers (155031601 and 305213961), so it is not a direct substitute for the standard 35A units. Double-check your original part number before ordering. For more on matching pump components, read our well pump with soft start.
Material Quality and Durability
Relays endure constant electrical load and environmental stress. Look for models made from high-quality ABS plastic and brass contacts, as these resist wear and corrosion. Products from JUWEVAZU and Pleoos emphasize these materials, while LDCRE uses a robust 35A design. A durable relay means fewer replacements and peace of mind.
Amp Rating and Electrical Specifications
Standard Franklin control box relays are rated at 35 amps. Most replacements match this, but the RVAH2ALKL offers 50 amps for higher power demands. If your pump draws more current or you want extra headroom, consider the 50A option. However, ensure your control box can handle the higher rating. For more on pump power requirements, see our complete well pump kit guide.
Ease of Installation
All these relays are designed for direct replacement. They come with clear instructions and require no special tools. Simply disconnect the old relay, plug in the new one, and secure the wires. The Formiden and JUWEVAZU models are particularly noted for their user-friendly design. If you are new to pump repairs, our well pump kit buying guide can help you understand the bigger system.
Final Thoughts
After reviewing all six relays, we recommend the rva2alkl Well Pump Relay from JUWEVAZU for its excellent balance of quality and value, and the Pleoos rva2alkl Control Box Well Pump Relay as a budget-friendly alternative that still delivers reliable performance. Both are direct replacements for Franklin 5 to 15 HP control boxes and come with durable materials. For those needing higher capacity, the RVAH2ALKL option from SZRKRLA is a solid choice, though it requires different part numbers. Whichever you choose, restoring your well pump is straightforward with these parts.
