PTC Resettable Fuses are special types of electrical circuit protection units that help to protect against catastrophic electrical damage. One of the primary applications of these devices is in the 250S130-RBDR. This is a circuit protection device used to protect against current overload in electronic circuits. Here, we present an overview of the 250S130-RBDR application field and its working principle.

The 250S130-RBDR is a solid state circuit protection device that uses a Resettable Polymer Thermal Cutoff. This PTC device is designed to be used in a variety of applications, including automotive, industrial, and consumer electronics. The PTC device helps to protect against over-current, under-current, and over-temperature events. The device is also capable of automatically resetting itself after an overcurrent or over-temperature event has occurred and the circuit has cooled down.

The 250S130-RBDR consists of a polymeric PTC element and a series of metal caps. The PTC element is connected in series with the metal caps with the internal resistor and fuse connected in parallel. The internal resistor provides a current path for the current generated by the PTC device. In normal operation, the current through the internal resistor is low, but when the current drawn from the PTC increases beyond the rated value, the PTC will be heated, causing the PTC to open and interrupting the current flow.

To protect against overcurrent or over-temperature events, the 250S130-RBDR also has a resettable mechanism. This resettable mechanism works by sensing the temperature of the PTC element and then triggering a reset mechanism if the temperature exceeds a pre-set level. This reset mechanism then forces the internal resistor back to its normal state, allowing the PTC device to again allow a current flow through the circuit.

The primary advantage of the 250S130-RBDR is its ability to reset itself after an overcurrent or over-temperature event has occurred and the temperature has been lowered. This helps to reduce the chances of any internal electrically short circuits or other electrical damage. In addition, the 250S130-RBDR also helps improve the overall efficiency of the electronic circuits it is being used in, as it allows more power to be drawn without the risk of overloading the circuit.

In conclusion, the 250S130-RBDR is a versatile circuit protection device that can be used in a variety of applications. It helps to protect against current overloads in electronic circuits, and also helps to improve the efficiency of the circuits it is used in. Furthermore, it has a resettable mechanism that can help protect against any type of electrical damage caused by overcurrent or over-temperature events.
