The TRA160 with PTC Resettable Fuses Through Hole P=5.1mm RoHS is a protective device designed to protect electrical and electronic circuits from overload damage. It has a current rating of 160 amps and a voltage rating of 300VAC. It features PTC technology, which utilizes a positive temperature coefficient (PTC) resistor to detect and respond to excessive current flows. When a short circuit or an overload occurs, the resistor from the device heats up and increases in resistance, stopping the hazardous current flow and resetting after a cooling-down period. The device meets RoHS standards, ensuring it is free of hazardous materials and safe for use in electric and electronic applications. Additionally, its through-hole connection allows for simple installation.
