Key Features & Capabilities

• 40 Amp Rating — handles continuous current up to 40 A before tripping, ideal for high-current circuits in boat or automotive systems.
• Manual Reset Design — compact push-button reset lets you restore circuit continuity immediately after a fault, eliminating the need to install or carry spare fuses. 
• High-Visibility Switch — the reset button is easy to see and operate even in low light or cramped conditions. 
• Waterproof & Ignition Protected — built to IP67 standards, this breaker can tolerate temporary immersion (up to 1 meter) and is SAE J1171 ignition-protected, making it safe for use in marine and engine compartments.
• Corrosion-Resistant Connections — terminals and internal contacts are treated to resist saltwater corrosion, ensuring a long-lasting, reliable connection in harsh environments. 
• Compact, Durable Construction — built for space-constrained installations where reliability matters, its form factor fits nicely in control panels, fuse blocks, or behind dashboards.
• Reduced Maintenance & Cost-Savings — because you reset the breaker instead of replacing a fuse, over time this cuts down on maintenance, downtime, and spare part inventory.

This resettable circuit breaker is ideal for marine audio systems, trolling motors, bilge pumps, power distribution, battery circuits, and other high-current marine/automotive circuits. It gives you the protection you need with the simplicity and durability demanded by tough environments.
