PTC Resettable Fuses are often used to protect electronic equipment against overloads and short circuits. The RUSB135 is a type of PTC Fuse which provides protection against fault currents up to 135A. It is a resettable device, meaning that when the overload is removed, the fuse will reset and can be used again without having to be replaced.The RUSB135 works by using a Polymer Positive Temperature Coefficient (PPTC) element. When power is first applied, the PPTC element is in its steady-state low resistance form. If the current flowing through the fuse exceeds its trip level, then the PPTC element will transition to its high resistance state. This reduces the current flow and causes the device to trip.The advantages of using a resettable fuse such as the RUSB135 include the fact that it can be used multiple times without replacing the device and its associated wiring, and it also does not require any specialised equipment and operator skills to reset it. Furthermore, the trip characteristics of the RUSB135 are adjustable, allowing it to be tailored to the specific needs of the application.The RUSB135 is widely used in a variety of applications, such as in motor protection, automotive, industrial, telecom, and those involving high starting current. It can be used to protect electric motors from overloading and short circuits, allowing them to run at maximum efficiency. It can also be used to protect sensitive electronic components from overvoltage.In terms of installation, the RUSB135 benefits from a range of mounting and connection options, including screw terminals, lug terminals, lap terminals and solder-lug terminals. The unit also features LED indicators for quick identification of overcurrent events in the circuit, making it easy to detect a fault before it becomes too serious.The RUSB135 also offers a safe operation due to its self-resetting capability. It is designed to self-reset when the overcurrent condition is removed, providing a high level of overcurrent protection along with a simple reset operation.Overall, the RUSB135 offers a cost-effective, dependable and adjustable overcurrent protection solution. Its ability to be reset multiple times without requiring replacement makes it an excellent choice for a variety of applications, while its wide range of connection and mounting options ensure it can be used for a diverse selection of projects.
