Stinger SCBM150 150-AMP Marine-Grade Circuit Breaker

150-Amp Circuit Protection Built for Marine and Powersports Sealed, Weatherproof, Easy Reset

Product Overview

The Stinger SCBM150 is a 150-amp marine-grade circuit breaker designed for applications where reliability, weather resistance, and protection against the marine environment are non-negotiable. Sealed for marine and powersports use, it carries marine-certified ignition protection a critical certification for fuel-vapour environments found on boats and marine vessels and is weatherproof for reliable performance in harsh conditions.

The SCBM150 provides 150 amps of circuit protection and features an easy reset and disconnect function, eliminating the need to replace a fuse after a trip. It accepts 5/16" ring terminals on both connection points, compatible with high-current automotive and marine wiring. Suited for boats, marine installations, ATVs, UTVs, and any powersports or off-road application requiring sealed, reset-capable overcurrent protection.

Features & Benefits

• 150A Circuit Protection — Provides overcurrent protection up to 150 amps, suitable for high-current marine and powersports circuits including main power feeds, amplifiers, and accessory circuits.
• Sealed for Marine and Powersports — The fully sealed housing prevents moisture, salt spray, and debris ingress, making it suitable for direct exposure in marine and off-road environments.
• Marine-Certified Ignition Protection — Certified to marine ignition protection standards, making the SCBM150 safe for installation in fuel-vapour environments on boats and marine vessels where ignition-protected equipment is required.
• Weatherproof — Rated for harsh weather conditions including rain, spray, humidity, and temperature extremes typical of marine and outdoor powersports use.
• Easy Reset / Disconnect — A manual reset function restores the breaker after a trip without replacing a fuse, and the disconnect capability allows the circuit to be manually opened for maintenance or isolation.
• 5/16" Ring Terminal Compatibility — Both terminals accept standard 5/16" ring terminals, compatible with heavy-gauge wire and marine-grade wiring accessories.

Frequently Asked Questions

What is the difference between a circuit breaker and a fuse?

A fuse is a one-time-use protection device that must be replaced after it blows. A circuit breaker trips when the current limit is exceeded and can be manually reset, restoring circuit protection without replacing any component.

Is the SCBM150 safe for use on a boat?

Yes — the SCBM150 carries marine-certified ignition protection, making it safe for installation in marine environments including areas where fuel vapour may be present. It is also fully sealed and weatherproof for marine conditions.

What does easy reset mean on this circuit breaker?

After the breaker trips due to an overcurrent event, it can be reset manually — restoring full circuit protection without replacing any components. The disconnect function also allows the circuit to be manually opened for maintenance or isolation without waiting for an overcurrent event.

What terminal size does the SCBM150 use?

The SCBM150 uses 5/16" ring terminals on both connection points, compatible with standard heavy-gauge marine and automotive wiring.

Can the SCBM150 be used in car audio or 4WD applications?

Yes — while designed to marine-grade standards, the SCBM150 is equally well-suited for high-current car audio power feeds, 4WD auxiliary circuits, and any application where a sealed, weatherproof, resettable 150A circuit breaker is required.
