6A USONIC Overload Switch Code: 60880263

A 6A Usonic overload switch (often branded or generically sold as a thermal push-button circuit breaker) is a safety device designed to cut power when the current exceeds 6A. It protects electrical equipment, branch lines, and motors from damage caused by overheating and overcurrents.

Core Specifications

• Rated Current:6A
• Rated Voltage:Operates on both AC (up to 250V) and DC (typically up to 32V or 48V)
• Reset Type:Manual push-button reset (pops out when tripped, pushed back in to restore power)
• Electrical Life:~10,000 operations
• Contact Resistance:≤ 40mΩ

Common Applications

• Branch lines inside power strips, surge protectors, and electrical panels.
• Small motors, air compressors, and battery chargers.
• Portable generators, welders, and power tools.

How It Works

Inside the switch is a calibrated bimetallic strip. When a current higher than 6A flows through the circuit continuously, the excess heat causes the strip to bend. This bending releases a latch, forcing the switch into the “OFF” position. Once the device cools down, you simply press the button back in to reset the connection.
