Frequently Asked Questions

Is this circuit breaker safe to use in a gasoline engine compartment?
Yes. This circuit breaker is SAE J1171 Ignition Protected, which means it is sealed and constructed to prevent sparks from escaping, making it completely safe for marine engine bays.
Can this breaker handle constant exposure to salt spray?
Absolutely. Built with a waterproof thermoset housing and corrosion-resistant hardware, the casing is designed to prevent marine salt spray and moisture from degrading internal electrical contacts.
How do you reset this circuit breaker after it trips?
When the breaker trips, the high-visibility red lever swings outward to signify a break. To reset, resolve the electrical fault first, and then push the red lever back into the nested housing until it clicks securely.

Our Roots

Hong Kong Based, 8 Years of Expertise

The story of AirowMarine began eight years ago. Headquartered in Hong Kong, we have been dedicated to the global operation and brand building of marine accessories. These eight years of experience have taught us that on the unpredictable sea, every single component carries the trust and safety of the boat owner.

Supply Chain

Invested Factories in Mainland China

To ensure our products withstand extreme environments, we are more than just a bridge for trade. AirowMarine has invested in its own manufacturing facilities in Mainland China. Leveraging the region's mature and efficient industrial supply chain, we are deeply involved in the entire process—from raw material selection and precision machining to final assembly. We avoid exaggerated claims; instead, through professional logistics and rigorous quality control, we ensure every product delivered to you meets high nautical-grade standards.
