PTC Resettable Fuses

PTC Resettable fuses, also known as PolySwitch, are re-settable circuit breakers that are designed to replace traditional fuses in many applications. They are a special type of positive temperature coefficient (PTC) thermistor that can be used to protect electronic circuits from over-current conditions. PTC Resettable fuses are designed to be easy to use, cost-effective, and reliable.

PTR030V0250-BK1 Application Field and Working Principle

The PTR030V0250-BK1 High Voltage PTC Resettable Fuse is designed to protect current circuits from over-current conditions in the fields of AC mains power distribution, medical products, telecom, electricity meter, amplifier and industrial control products. The product has a higher power rating and wider compliant voltage range up to 250V. It is also RoHS compliant and UL recognized to UL774E and CE certified as per EN60146-1.

The PTR030V0250-BK1 is composed of a PTC actuator (Polyswitch) and a spring. When the current level exceeds the rated value, the temperature of the Polyswitch increases, and the spring conducts heat into the atmosphere. This causes the Polyswitch to switch into an open circuit state, thereby preventing further current flow in the circuit.

After the current has returned to normal, the device slowly cools down and the spring pulls the Polyswitch back into the closed position, reactivating the circuit. Thus, the PTR030V0250-BK1 provides a safe and economical way to protect circuits from over-current conditions.

The device is designed for over-current protection of 230VAC mains power distribution, can be applied to critical medical and telecom products. It provides fast switching time and can be used in all types of AC operations. In addition, the PTR030V0250-BK1 is highly reliable, with low internal resistance and low leakage current.

Overall, the PTR030V0250-BK1 is an effective and reliable protection device, designed to keep current circuits safe from over-current conditions. Its high power rating, wide compliant voltage range, and RoHS compliant construction make it a viable option for a variety of applications.
