LA070URD31KI0250

The LA070URD31KI0250 is an electrical specialty fuse designed to provide circuit protection. It is capable of interrupting high short-circuit currents with a minimum time-lag. The LA070URD31KI0250 has a dual-element fuse that can be used in many types of industrial and commercial applications. The LA070URD31KI0250 fuse is designed to meet UL, CSA, and CE requirements.

The LA070URD31KI0250 has a high breaking capacity of up to 35 kA at 415 volts AC and up to 70 kA at 230 volts AC. It also has a range of other features such as a 42 kHz frequency response, low operating temperature, low voltage noise protection, and enhanced arc fault current interruption. The fuse can be easily reset by a reset switch due to its anti-tail establishment.

The LA070URD31KI0250 application field includes motor contactors, electric cars, UPS systems, circuit breakers, welding machines, and other industrial machinery. It is also suitable for a wide range of UL and CSA-listed industrial and commercial power distribution applications. The fuse is also UL recognized as a component that can be used in UL-certified industrial and consumer electronics.

The LA070URD31KI0250 has a dual-element design with a high temperature rating that allows for reliable thermal stability. The fuse is capable of interrupting high short-circuit currents in a fast and reliable manner due to its time-lag rating. The fuse also has a low-voltage protection that prevents arc fault current interruption and eliminates dangerous power surges.

The working principle of the LA070URD31KI0250 is simple. It consists of two elements: a metal fuse link and a pressure-sensitive incendiary element. The metal fuse link is designed to heat up and melt under a high short-circuit current. The pressure-sensitive incendiary element will then fail, allowing the high current to pass through the fuse and create an arc. Once the current is reduced to a safe level, the arc is extinguished and the fuse resumes normal operation.

The LA070URD31KI0250 is an ideal fuse for industrial and commercial applications. It is designed to provide reliable circuit protection for motor contactors, electric cars, UPS systems, circuit breakers, welding machines, and other industrial machinery. The dual-element design, high breaking capacity, and anti-tail establishment make it an ideal choice for power distribution applications.
