PTC Resettable Fuses

PTC Resettable Fuses are an overcurrent protection device designed to open and reset a circuit, protecting it from dangerous electrical surges. Rather than burning out as traditional fuses do, these resettable fuses react to an overcurrent condition by "tripping" and shutting off the circuit until the fault is removed. This is achieved through the use of a small Positive Temperature Coefficient (PTC) resettable device such as the MF-PSML 260-2.

The MF-PSML 260-2 is a single-element PTC resettable fuse, designed with a unique thermal cut-off which opens the connection when the current through it exceeds a certain level. When the current falls below the required level, the thermal cut-off automatically reconnects the circuit. This resettable fuse is suitable for a wide range of motor applications, including automotive, bus, and rail. It has a higher interrupting capacity than traditional resettable fuses, allowing it to handle higher currents. It also has a higher thermal endurance than other PTC devices, making it more reliable and durable.

The MF-PSML 260-2 is designed to provide protection in the event of an overcurrent situation. It will open the circuit and trip the protection device, cutting off the power supply and protecting the circuit from further damage. The device can then be reset, and the power is automatically reconnected once the fault is cleared. This resettable fuse is also designed to protect against surges in power, making it an ideal solution in applications where a surge protector is not available. In addition, it has a wide operating voltage range, making it suitable for use in a variety of applications.

The working principle of the MF-PSML 260-2 is fairly simple. When the current through the device exceeds a predetermined level, the internal fuse trips, cutting off the power supply. The user can then reset the fuse by manually switching off the power supply and switching it back on once the fault has been cleared. The internal fuse will then reset, reconnecting the power supply and allowing the device to resume operation. This resettable fuse can be used in multiple applications in order to protect from overcurrent and surges in power.

The MF-PSML 260-2 is an ideal choice for many applications due to its high interrupting capacity and long-lasting performance. It can act as an effective overcurrent protection device, providing reliable short-circuit protection in both residential and commercial applications. By protecting a circuit from power surges and dangerous current levels, this resettable fuse can help keep electrical systems safe and functioning properly. This is why it is a popular choice for many different applications, from automobiles to industrial machinery.
