HAY-PSU412-10A 12V 4 way boxed PSU 10Amp Ptc Fuses & S/Protected. The PTC resettable fuse by Haydon is a new-type of overcurrent protection element which has two functions providing overcurrent protection and automatic reset. The overcurrent protection PTC element is serially connected to the circuit and under normal circumstances it provides a low resistance state and can ensure the normal working of the circuit.

If a short circuit or unusually high current occurs, then the PTC fuses cut in to reduce the voltage down to a trickle thus preventing damage and protecting the equipment. The PTC fuse will automatically reset once the fault in the overcurrents removed. The PTC elements will automatically return to its low resistance state. Not only avoiding maintenance or replacement, but also avoids a continuously circulating switching state which can cause circuit damage.
