Introduction to PTC Resettable Fuses

PTC resettable fuses are electrical circuits components that are able to detect and respond to an overcurrent condition in an electric circuit. Oftentimes, these fuses are used to protect circuit boards from damage due to any unexpected or often unknown overload current. In these cases, PTC fuses are sometimes referred to as ‘overcurrent protection circuits’.These PTC fuses are composed of a polymeric material which contains a conductive particle. The polymeric material acts like a semiconductor, and when an overcurrent condition is detected, the conductive particles cause the resistance of this semiconductor to rise exponentially. This causes the material to heat up and, ultimately, trip the circuit by interrupting the current flow.

RL6315-50-110-240-PTO

RL6315-50-110-240-PTO is a type of PTC resettable fuse that has been designed for use in higher power applications. It is able to detect and protect circuits against short circuit currents of up to 63A and operational currents of up to 15A. It has a voltage rating of 110-240V.RL6315-50-110-240-PTO has a high breaking capacity of up to 6kA, which makes it suitable for use in industrial and automated machinery. Additionally, it has a ‘push to reset’ feature which enables fast and easy resets.

Application Field and Working Principle for RL6315-50-110-240-PTO

RL6315-50-110-240-PTO is most suitable for use in industrial and automated machinery, as it is able to protect the circuits against short circuit currents of up to 63A. It also has a voltage rating of 110-240V, and a high breaking capacity of up to 6kA.In its functionality, RL6315-50-110-240-PTO works by detecting any current above the rated operational current, or short circuit current as set by the manufacturer. Once detected, the PTC fuse will cause the resistance of the semiconductor polymeric material to exponentially rise. This will cause the material to heat up and ultimately trip the circuit, interrupting any further current astray.For the ‘push to reset’ feature, this is accomplished by the simple pressing of the reset button, which will cause the internal resistance of the fuse to drop again and reset the circuit.In conclusion, the RL6315-50-110-240-PTO fuse is a type of PTC resettable fuse which is suitable for use in industrial and automated machinery due to its high breaking capacity and ability to detect and protect against short circuit currents of up to 63A. It has a voltage rating of 110-240V and a ‘push to reset’ feature which enables a fast and easy reset process.
