RED WOLF 150A Manual Reset DC Circuit Breaker 12-48V with 5/16" (M8) Stud, Panel Mount

RED WOLF 150A manual-reset DC circuit breaker provides reliable overload and short-circuit protection for 12–48V vehicle and marine electrical systems while combining a switch and resettable breaker in one compact unit.

Built to safeguard batteries, stereo systems, trolling motors and off-grid power setups, this RED WOLF breaker replaces an inline fuse holder and offers a convenient manual reset for quick recovery after a trip. Constructed from heat-resistant materials and vibration-tolerant components, it operates across a wide DC voltage range and mounts easily on a panel or firewall using the 5/16" (M8) stud terminals.

How will this breaker protect my boat or vehicle electrical system?

The 150A breaker interrupts excessive current to prevent wiring and device damage from overloads or short circuits. Instead of a single-use fuse, it trips under fault and can be manually reset after the issue is corrected, reducing downtime and replacement parts.

• Trips at excess current to prevent wiring overheating and component damage
• Resettable design avoids repeated fuse replacements
• Suitable for trolling motors, car audio amps, and battery banks
• 5/16" (M8) studs for common marine and automotive ring terminals

Will it work with my 12V car, 24V trolling motor, or 48V solar system?

This model is rated for DC systems from 12V up to 48V, making it a versatile protection device across common vehicle, marine and small off-grid power configurations. Check your system’s continuous and peak current needs against the 150A rating to ensure correct sizing.

• Voltage compatibility: DC 12–48 volts
• Ideal for car audio, RV, boat, and small solar arrays
• Use as primary protection for batteries, inverters, and large loads
• Not a substitute for proper wire sizing—match wiring to expected current

How do I install and operate the RED WOLF manual reset breaker?

Mount the breaker on a panel or firewall using its base and connect battery and load cables to the 5/16" (M8) studs with suitable ring terminals and hardware. If the breaker trips, press the manual reset button once the fault is cleared to restore power.

• Mountable on panel or firewall for tidy installations
• Connect with 5/16" (M8) ring terminals and properly torqued nuts
• Manual reset button enables swift recovery after trip events
• Replace or upgrade wiring if persistent tripping occurs

Who is this for? Installers, DIY enthusiasts and fleet owners who need a durable, reusable overload protector for cars, trucks, RVs, boats and small solar or battery systems will benefit from this RED WOLF 150A breaker. It’s aimed at users who want a compact, heat-resistant circuit protection device that combines a switching function with resettable safety—ideal where access for fuse replacement is inconvenient or repeated trips are expected during troubleshooting.
