These Thermal Circuit Breaker Reset Switches are high-reliability safety components designed to protect electrical circuits from damage caused by excess current or overloads. Featuring a compact, panel-mount design with a manual "Push-to-Reset" button, these switches act as a resettable fuse, providing long-term protection for industrial and consumer electronics.
Automatic Overload Protection: Automatically trips and interrupts power when the current exceeds the rated limit, preventing overheating and potential fire hazards.
Manual Reset Functionality: Once the overload issue is resolved, the circuit can be easily restored by simply pressing the black reset button, eliminating the need to replace blown fuses.
Comprehensive Amperage Range: Available in 5A, 10A, and 20A variations to suit a wide spectrum of power requirements, all rated for up to AC 250V.
High-Conductivity Terminals: Equipped with two heavy-duty male spade terminals (Line and Load) for secure, low-resistance electrical connections.
Panel-Mount Ready: Features a threaded neck and knurled plastic nut for stable, vibration-resistant installation into circular panel cutouts.
Certified Safety Build: Constructed with flame-retardant housing and marked with international safety certifications (CE, CCC) for guaranteed performance.
Product Type: Thermal Overload Circuit Breaker.
Voltage Rating: AC 125/250V (also compatible with DC 32V/50V systems).
Current Options: 5 Amp, 10 Amp, or 20 Amp.
Reset Type: Manual Push-Button.
Terminal Interface: 2-Pin Male Quick-Connect.
Housing: High-strength Thermoplastic.
Application: Ideal for power strips, portable generators, air compressors, marine panels, and electric vehicles.
What causes the button to pop out? The button pops out when the thermal element inside expands due to heat generated by excessive current (overload). This is a safety feature that physically breaks the connection to protect your equipment.
Can I use a 20A switch to replace a 10A switch for "better" performance? No. You should always match the amperage of the switch to the original manufacturer's specifications of your device. Using a higher-rated switch than necessary may allow too much current to flow, potentially damaging your device before the switch trips.
How long should I wait before resetting? Since these are thermal breakers, you must allow a few seconds (usually 30–60 seconds) for the internal bimetallic strip to cool down before the reset button will stay engaged.
