12A USONIC Overload Switch Code: 03814620

A 12A overload switch (often called a thermal circuit breaker or resettable fuse) is a safety device designed to automatically cut off power if the electrical current exceeds 12 Amps. It protects compressors, electric motors, and power tools from overheating and electrical damage.

Key Details & Specifications

• Functionality:Interrupts the electrical circuit during continuous over-current conditions.
• Operation Type:Normally closed (NC) contact; when it trips, it physically opens the circuit.
• Reset Mechanism:Typically manual reset. Once the switch cools down, the user presses a push-button to restore power.
• Voltage Rating:Usually dual voltage compatible, rated for both 125V and 250V AC.
• Typical Application:Used in air compressors, water dispensers, high-draw household appliances, and industrial branch lines.
