PTC Resettable Fuses

PTC Resettable Fuses are specially designed circuit protection devices, which are mainly used to protect electrical and electronic circuits from overcurrent fault. They can sense the current flow and detect any fault current which could be damaging to the circuit. Once the current level exceeds the specified load, the PTC resettable fuses provide fast and reliable protection by tripping the circuit and interrupting the current flow. They are simple to install, compact in size, and offer higher load current rating.The PTCCL09H171HBE is a PTCfuse manufactured by the Phoenix Connector Company. It is designed to provide premium overcurrent protection to a variety of applications such as AC power supplies, electronic appliances, and motor controllers. The device uses a two-stage trip mechanism for sensitive overload protection and is RoHS compliant. It offers a high current rating of up to 1.71A and its quick trip rate ensure fast circuit response to prevent possible damage. The high current loading also ensures reliable operation with very minimal power loss.The working principle of the PTCCL09H171HBE is based on the PTC thermistor. A PTC thermistor is a temperature-sensitive resistor, the resistance of which increases with the increase of temperature. When an overcurrent fault occur in an electrical circuit, the heat generated by the current flow raises the temperature of the PTC fuse, and in turn increases its resistance. This causes the current flow through the effective resistance of the fuse to be reduced, and ultimately, the fuse trips, cutting off the power supply to the circuit. When the fault current is removed, the device re-sets to its normal operating state.The PTC resettable fuses are ideal for industrial and residential applications due to their long-term reliability and cost-effectiveness. The PTCCL09H171HBE is suitable for a variety of applications such as industrial equipment, medical apparatus, industrial control systems, automotive electronics, and aerospace devices. It is cost-effective due to its long-term stability and durability. Furthermore, the device is highly compatible with a variety of components and can be easily integrated into existing systems.To sum up, the PTCCL09H171HBE is a sophisticated PTC resettable fuse, designed for overcurrent protection of electronic circuits. This device has a high load current rating, which makes it suitable for use in a variety of systems. It has a quick trip rate and its Reset mechanism ensures the safe operation of the system. Moreover, the device is easy to install, cost-effective, and provides a long-term reliability. Therefore, it is the perfect choice for a range of industrial and residential applications.
