PTC resettable fuses are devices specifically designed to act as a thermal switch and are used in many electrical and electronic systems for protection against faults. RUEF900K-2 is a PTC automotive fuse that provides protection for a wide variety of systems, including lead-acid batteries, alternators, auxiliary power units, and power seats.

RUEF900K-2 has a self-resetting thermal switch actuated by a thermally fused metal strip, which is made from a combination of metals that rapidly react to increased temperatures. The thermal fuse reacts to excessive current, which creates heat, which in turn causes the metal strip to expand and push a plunger-like mechanism within the PTC device that opens the PTC switch contacts. This opens the device’s circuit, stopping the current.

When the excess current has stopped, the metal strip cools and contracts, allowing the plunger to reset. This re-closes the switch contact, re-enablingthe circuit with no further action. This process eliminates the need to manually reset the fuse after a fault has occurred. The RUEF900K-2 is designed with a current rating of 30A @ 12V DC.

RUEF900K-2 has a wide range of applications, most notably in automotive systems. It can be used to protect the batteries, alternators, auxiliary power units, and power seat circuits from faults or overloads. Additionally, it can be used as a secondary protection device in safety-critical systems, such as airbag deployments, and can be used to protect against lightning strikes in audio systems.

RUEF900K-2 has a number of advantages over traditional fuses. Its resetting nature eliminates the need for manual fuse replacement, and its protective action does not degrade over time like a traditional fuse. Additionally, it is inexpensive and can be found in a variety of sizes and shapes to fit many different applications. Its thermal fuse also ensures reliable protection against fault currents that may exceed the fuse rating, and can be used in applications where it may be exposed to a wide variety of temperatures.

In conclusion, the RUEF900K-2 PTC resettable fuse provides effective protection from fault current and overloads for automotive systems and other safety-critical systems. Its thermal switch actuated by a thermally fused metal strip resets itself automatically, and its small size and wide temperature range make it a perfect fit for a variety of systems.
