PTC Resettable Fuses are switching devices that are used to protect circuits from excessive current. They are designed to trip when a preset threshold is exceeded, without burning out, and are reset using an external reset circuit. The HVR250P120CRFF is a PTC Resettable Fuse designed to trip at 250 Amps of continuous current, with a trip time of approximately 2 milliseconds at 120 volts.

Application Field

The HVR250P120CRFF is typically used in automotive, industrial, lighting, and consumer electronic applications to protect against shorts, overloads, and over-voltage situations. It is designed to protect against continuous current up to 250 Amps, with a burn-through time of less than two milliseconds. The PTC Resettable Fuse can be used to protect against over-currents and shorts, as well as against short circuits.

The HVR250P120CRFF is an ideal choice for applications that need reliable over-current protection. It is typically used in applications such as starter motors, battery chargers, lighting circuits, and other electrical systems. It is also suitable for applications with high inrush currents, such as motors, transformers, and power supplies.

Working Principle

The HVR250P120CRFF is a PTC Resettable Fuse, which works on the principle of a Polymer Positive Temperature Coefficient (PPTC). When a preset current threshold is exceeded, the PPTC element within the fuse trips, causing it to open the circuit.

Once the current is reduced, typically by turning the device off, the PTC element within the fuse cools down and can be reset using an external control circuit. The PTC element acts like a tiny switch; when it is triggered, it allows current to flow through it, and when the current is below the preset threshold, it opens the circuit, stopping current from flowing.

The HVR250P120CRFF is a fast, reliable, and safe solution for over-current protection in many applications. It combines the benefits of traditional fuses with a programmable reset circuit, ensuring that the circuit is protected and can be reset quickly and easily.
