25A Thermal Circuit Breaker - Pack of 2

Key Features

  • Automatic Overload Protection: Specifically designed to protect electrical circuits and sensitive equipment from damage caused by current overloads. The breaker will "trip" and pop out the button when the current exceeds 25 Amps.
  • Dual AC/DC Versatility: Fully rated for both AC (125V/250V) and DC (32V) applications, making it a universal safety component for household appliances, marine vessels, and automotive electrical systems.
  • Manual Push-to-Reset: Features a reliable "trip-free" design where the breaker cannot be held "ON" during an ongoing overload. Once the fault is cleared, a simple press of the manual button restores the circuit.
  • Waterproof Protective Caps: Includes high-clarity silicone screw-on caps that provide an IP64-rated moisture and dust seal, protecting the reset button and internal mechanism in marine or outdoor environments.
  • Quick-Connect Terminals: Equipped with standard 0.250-inch (6.3mm) male spade terminals, allowing for fast, solderless wiring connections using standard female crimp connectors.

Replaces / Cross-Reference Part Numbers

  • Industry Standards: Series 58, W58-Type, KUOYUH 88 Series.
  • Marine/Automotive Codes: MRCB-25A, 11210-25, 42-25A.
  • Manufacturer Equivalents: Joemex PE74, Tyco W58-XB1A4A-25, Potter & Brumfield W58 series.
  • Kit Components: Includes 2x 25A Breakers, 2x Waterproof Caps, 2x Mounting Nuts, and 2x Nameplate Screws.

Compatibility & Fitment

This 25-Amp protector is a standard safety component for a wide range of power distribution and appliance applications. Key compatible use cases include:

  • Marine & RV: Fits DC fuse panels and switchboards for boats, yachts, motorhomes, and campers (e.g., SeaFlo, Blue Sea Systems style panels).
  • Small Appliances: Used in air compressors, pressure washers, floor scrubbers, and high-draw kitchen appliances.
  • Power Equipment: Common in portable generators, battery chargers, and power strips to prevent total circuit failure.
  • Industrial Tools: Fits many bench grinders, drill presses, and woodworking machinery control boxes.
  • Note: This is a Thermal breaker. It is designed to ignore short-duration "startup surges" but will trip during sustained overloads.

When to Replace

  • Breaker Won't Reset: The button will not stay pushed in even after the appliance has cooled down and the load is removed, indicating internal mechanical failure.
  • Nuisance Tripping: The breaker trips at currents well below 25 Amps, suggesting the internal bimetallic strip has become "weak" or calibrated incorrectly due to age.
  • Visible Heat Damage: The black plastic housing is melted, discolored, or charred near the terminals, often caused by loose wiring connections creating localized resistance.
  • Corroded Terminals: In marine environments, green or white oxidation on the metal spade lugs can prevent electrical flow or cause the breaker to overheat.
  • Loose Reset Button: The button feels "mushy" or fails to provide a distinct clicking sound when reset, indicating a broken internal spring.

Installation Tips

  • Safety First: **CRITICAL:** Ensure the power source (Battery or AC Mains) is completely disconnected before installation. Touching live terminals can result in severe shock or short circuits.
  • Check Wire Gauge: For a 25-Amp circuit, ensure you are using at least 10 AWG or 12 AWG copper wire. Using thinner wire can cause the wiring to overheat before the breaker has a chance to trip.
  • Mounting Hole: This breaker typically requires a 3/8-inch (10mm) round mounting hole. Ensure the panel thickness is within 0.03" to 0.10" for the mounting nut to thread securely.
  • Terminal Tension: Ensure your female spade connectors are tight. If they slide on too easily, use pliers to gently crimp the connector for a firm, low-resistance "friction fit."
  • Avoid Overtightening: When installing the waterproof cap, tighten it only until the silicone seal is snug against the panel. Overtightening can strip the plastic threads on the breaker body.

Great invention
Color: White
Second pack of these and I love them. I used them mostly for computer cables in my home office and my work office so I did not constantly have to go digging for laptop power cords and adapters. They have a strong adhesive that is very durable, the installation was super easy, super functional and overall great value for the money. These would be versatile as well if you wanted to use them for say phone charging cables or similar cords that seem to always fall behind a shelf or something similar.

Wonderful for chargers
Color: White
I was skeptical about ordering these, but I am so glad I did. They are little cord controllers and they have a lift up cover that is magnetic so you can easily take your cord out of the hole. They stick to what you put it on and I’ve had no problem with them coming off on wood or plastic. Glad I bought these.

Easy and Effective
Color: White
These are slick little gadgets! They hold a cord so it doesn’t fall behind a table or chest. I affixed one to the side of our nightstand and my phone charges there all night. Genius- no installation skills required.

Perfect to plug in and off the floor.
Color: White, Color: White
These are perfect for keeping the charging cords organized. I have difficulty reaching the floor when I need them. I work from home and need to charge my phone and laptop often. So far the adhesive is holding up. The magnet is strong enough and the cord is light weight and does not slip through the hole. I have usB and C cords. We use them at the side of bed for our cell phones. It’s on the side of our nightstand. Makes vacuuming easier to. The cord is off the floor. Overall happy with these. Worth the money.
