Replaces / Cross-Reference Part Numbers

Serves as a reusable replacement for any standard 150A single-use fuse (such as ANL or MAXI style fuses) when used with an appropriate fuse holder. Direct replacement for surface-mount 150A circuit breakers with identical voltage ratings and stud terminal configuration.

Compatibility & Fitment

Designed for overcurrent protection in high-current 12V to 48V DC systems. Common applications include:

  • Automotive and car audio amplifier systems
  • Marine electrical systems, trolling motors, and winches
  • Recreational vehicles (RV) and auxiliary battery setups
  • Solar power systems and battery banks
  • Heavy-duty industrial equipment

When to Replace

  • Existing breaker fails to trip during an overload or short-circuit event.
  • Nuisance tripping occurs under normal, rated current loads.
  • The manual reset lever is broken, loose, or will not stay in the "ON" position.
  • Visible signs of damage, such as a cracked housing or severe corrosion on terminals.
  • As an upgrade from a standard 150A fuse to a resettable circuit protection device.

Installation Tips

  • Always disconnect the battery or power source before starting installation.
  • Install the breaker as close to the power source as possible to protect the main power wire.
  • Ensure wire-to-terminal connections are secure using properly crimped ring terminals to prevent overheating.
  • Use a wire gauge appropriately sized for a 150A load to avoid voltage drop and fire risk.
  • Do not use the manual trip lever as a routine power switch.

FAQ

These breakers are designed for high-amperage DC electrical systems, commonly used in marine trolling motors, automotive audio systems, RV power distribution, battery charging systems, and solar power setups where overcurrent protection is required.
These are manual reset breakers. When a fault occurs, the internal mechanism will trip, and the reset lever will physically move to the 'off' position. You can visually inspect the lever; if it is in the tripped position, you will need to manually push it back to the 'on' position once the underlying electrical fault has been resolved.
Yes, the manual reset lever allows you to use these breakers as a convenient disconnect switch. You can manually trip the breaker to cut power to your equipment for maintenance or storage without needing to remove the fuse or disconnect the battery terminals.
For a 150-amp load, you must use wire sized appropriately to handle the current without overheating. We recommend using at least 2 AWG or 1/0 AWG copper wire, depending on the length of your cable run, to ensure minimal voltage drop and safe operation.
These breakers feature a water-resistant housing designed to protect the internal components from moisture and dust. While they are suitable for engine compartments and marine environments, they should not be submerged in water.
