FAQ

These breakers are rated for 3 Amps and are compatible with 125/250V AC circuits. They also support up to 32V DC applications, making them versatile for various household appliances and power equipment.
This is a manual reset thermal circuit breaker. If the circuit trips due to an overload, you must manually press the button to reset the connection once the device has cooled down.
Each breaker measures approximately 35mm x 31mm x 14mm. They are designed for panel mounting and feature a standard threaded mounting shaft with a diameter of 9.8mm and a pitch of M11*1.0.
You likely need a replacement if the device fails to reset after an overload, if the reset button feels loose or fails to 'click' into place, or if the breaker trips repeatedly under normal operating loads. Always check for external shorts or motor issues before replacing the breaker to ensure the new one does not trip immediately.
Installation typically requires a pair of needle-nose pliers for the 1/4" tab terminals and a wrench or socket to secure the mounting nut to the panel. Ensure the power is disconnected from the equipment before beginning the installation.
These breakers are designed to function reliably in environments ranging from -10°C (14°F) to 60°C (140°F).
