PTC resettable fuses are designed to provide reliable over-current protection for power supplies and other sensitive components in a circuit. The PTC resettable fuse, PTCTZ3NR949ETE, is a 3A/250VAC/50VDC PTC resettable fuse that is able to reset after a period of time without the need for user intervention.

The PTCTZ3NR949ETE is designed to protect power supplies, motors, solenoids, transformers, and other components that may be vulnerable to over-current surges or short circuiting. It is ideal for use in residential and commercial appliances such as TVs, refrigerators, air conditioners, and other appliances that may be vulnerable to surges. The fuse has an internal heat sink to dissipate over-current heat and a high-temperature plastic casing to protect the fuse from external environmental hazards.

The PTCTZ3NR949ETE is designed to detect and react to both over-current and over-temperature conditions. When an over-current situation arises, the PTC element will raise its resistance and cause the current to drop. This will reduce the amount of energy dissipated in the circuit, preventing damage to the components. If the over-current persists for a certain amount of time, the PTC element will permanently open and the fuse will be destroyed.

In the case of an over-temperature situation, the PTC element will react by increasing its resistance. This will cause the current within the circuit to drop, limiting the amount of heat generated by the circuit and preventing damage. Once the temperature returns to normal levels, the PTC element will reset itself and the circuit will return to normal.

The PTCTZ3NR949ETE is easy to install as it is designed to fit into most standard fuse holders. The fuse can be easily replaced in the event of a failure without needing to replace the entire circuit. The device is compliant with the IEC 62321 safety standard, making it suitable for international applications.

The PTCTZ3NR949ETE is an ideal choice for applications where reliable, maintenance-free protection from over-current and over-temperature is required. The fuse is a cost-effective solution and can help avoid costly system damage due to power failures and surges. The PTCTZ3NR949ETE is a reliable way to protect your circuits from potential faults and damaging surges.
