0ZRA0400FF2D

PTC resettable fuses are current-limiting polymeric positive temperature coefficient protection devices that are designed to open an electrical circuit when an overcurrent fault occurs and then, after the fault current drops below a certain level, reset. This type of circuit protection device is seen as an alternative to standard short-circuit protection devices such as fuses and switches.

The 0ZRA0400FF2D is a PTC resettable fuse designed for use in a variety of applications, including automotive, consumer, industrial, and medical applications. It is designed with an integrated control circuit and uses a PTC element to protect the circuit from overcurrent faults. The 0ZRA0400FF2D has a maximum voltage of 32 volts and a maximum current of 4 amps.

The working principle of the 0ZRA0400FF2D is based on the PTC polymeric positive temperature coefficient technology. This technology uses a temperature-sensitive PTC element that is designed to disconnect the circuit when an overcurrent fault occurs. When a fault occurs, there is an increase in the current flowing through the PTC element, which causes the temperature of the element to rise. This increase in temperature causes the PTC element to increase its resistance, effectively disconnecting the circuit and preventing the overcurrent fault.

When the fault current drops below a certain level, the PTC element will cool and the resistance of the element will be decreased. This will allow the circuit to be reset and the overload to be cleared, thus allowing the circuit to continue to operate normally. The 0ZRA0400FF2D can be used in a variety of applications, and its integrated control circuit allows for easy setup and modification.

The 0ZRA0400FF2D is an ideal choice for applications that require circuit protection from overcurrent faults. It provides accurate overcurrent protection and can be easily reset after a fault occurs, thus preventing potential damage to the circuit. The 0ZRA0400FF2D is well-suited for a variety of applications including automotive, consumer, industrial, and medical applications.
