Electrical specialty fuses are used to protect circuits from over current damage. The SPXV020.L is a high-performance dual-element fuse featuring two separate and independent sets of current-limiting power elements over a wide current range with lower operating voltage and higher interrupting levels. It is designed for protection of equipment and components in a variety of electrical power distribution, motor control and electrical control applications.

The SPXV020.L fuse requires a very low voltage to open and, compared to other fuses, performs well in applications that require high fault currents and can handle large inrush of current during starting or transients. It is also ideal for applications where a power failure is not an option and where an increased I2t is needed.

The SPXV020.L uses two separate and independent sets of current-limiting power elements. The first element is a power element with a rated current of 200A. The second element is a shunt element that is connected in parallel with the power element. It has a lower rated current of 20A and is specifically designed to limit high-frequency current inrush.

When a high current surges, the power element opens, first limiting the current and then reducing it to a level below that of the second element. When the current decreases, the power element closes and a pocket of air is created. The pocket amounts to a small capacitor and provides a delay in current transition for a few milliseconds. This delay increases the time it takes for the shunt element to open, allowing the current to rise slowly and smoothly.

The SPXV020.L features superior life capacity and cuts off the current without generating mechanical noise or arcing electrodes. It operates within the temperature rating of -55 to +125°C and is available in both single, dual and multi-pole package versions. Its power element provides protection when the current passes through the fuse in a single direction. It also features a very fast acting response if the current is higher than the control current.

The SPXV020.L is widely used in electronic systems, such as medical equipment, industrial tools, pumps, motor control, household appliances, HVAC systems, and solar panels. Its dual-element design also makes it suitable for renewable energy applications and in extreme temperature and voltage conditions.

The SPXV020.L fuse is an ideal choice for applications requiring protection from large inrush currents and is also a great option for applications that require higher operating voltages and interrupting levels. Its fast operating response, superior life capacity and reliable operation make it a great choice for applications that need to be wired quickly, safely and reliably.
