Push-Button Circuit Breaker with Manual Reset (3–25A, 32V DC)

Say goodbye to replacing blown fuses – this push-button circuit breaker provides reliable overload protection that can be reset with a simple push. Built around a heat-sensitive bimetallic element, the breaker will trip (open the circuit) when current exceeds its rated amperage, protecting wiring and equipment from damage. Once tripped, its button pops out visibly to indicate the fault. After resolving the cause of the overload, you can manually reset the breaker by pressing the button back in, instantly restoring the circuit without needing any replacement parts. This breaker is designed for DC circuits up to 32 volts (common in 12V and 24V systems) and is available in a range of current ratings: 3A, 5A, 7A, 10A, 15A, 20A, and 25A. Selecting the appropriate amp rating ensures your specific circuit (whether it’s lighting, a pump, electronics, etc.) is properly protected – the breaker will trip if current draws above that threshold. The device’s form factor is compact and panel-mount: it has two screw terminals at the back for input and output, and the front features the round reset button. The front face typically measures about 35×59 mm with mounting holes or a nut, allowing easy installation on a control panel or near the equipment it protects. Marine application: The breaker’s components are encased in a plastic housing with a water-resistant push button (often with a rubber cap or O-ring) to tolerate humid and damp conditions on board (though it’s recommended to mount it in a relatively sheltered location or inside a panel box for full longevity). With these resettable breakers, you enhance safety – they respond faster than many fuses and eliminate the risk of running with an oversized or bypassed fuse. Additionally, recovering from an electrical fault is straightforward: there’s no fumbling for spare fuses; a quick press gets you back in operation once you’re sure it’s safe. They are widely used for circuits like bilge pumps, windlass controls, navigation lights, and electronics where manual reset is advantageous. These push-button breakers are also trip-free – meaning if the fault persists, the breaker will not stay engaged even if you hold the button in, thereby ensuring continuous protection. Upgrade your electrical panel with these economical and reliable circuit breakers and gain peace of mind knowing your wiring is safeguarded with a simple push-button solution.
