PTC Resettable Fuses are components that are widely used in electrical installations and devices. They provide overcurrent protection and are usually placed in parallel with the device or appliance they are protecting. This is a short overview of the PTR030V0700-TR variant of these components, its application field and working principle.

The PTR030V0700-TR is a radial leaded positive temperature coefficient (PTC) Polyfuse. It has a Resistance Value (RV) of 90 Ohm. Its maximum current rating is 30A and the maximum breakover current is 150A. It is CE approved and complies with EN60730-2-7. This particular component is suitable for power supply unit, industrial control, Set Top Box, and HVAC applications.

The working principle of PTC Resettable Fuses is simple - when a short circuit or overload occurs, the PTC will go into a high resistance state. The PTC absorbs large amounts of energy, which causes it to heat up. This increases its resistance and drastically reduces the flow of current. This drop in current also results in a reduction of heating. The PTC will remain in this high resistance state until it has cooled down again, at which point the resistance reverts to its normal level.

These components can be used in a variety of applications from residential to commercial and industrial settings. The PTR030V0700-TR is a good choice for applications such as power supply units, industrial control systems, set top boxes, HVAC systems and other related equipment installations. It can also be used where reliability and safety of operation are desirable. This component can also be used in other applications provided that its ratings are not exceeded.

In summary, the PTR030V0700-TR is a radial leaded positive temperature coefficient (PTC) Polyfuse with a Resistance Value (RV) of 90 Ohm, maximum current rating of 30A and maximum breakover current of 150A. Its applications include power supply units, industrial control systems, set top boxes, HVAC systems and other related equipment installations. Its working principle is based on the ability of the PTC to switch to a high resistance state when an overload or short circuit is encountered, thus providing reliable and safe operation.
