PTC resettable fuses are current-sensitive devices made with a specialty thermoplastic material that monitors electrical current flow and provides circuit protection when overloaded or shorted out. Resettable fuse, or Polymeric Positive Temperature Coefficient (PPTC) devices, are an alternative for overcurrent protection without the typical cost or complexity of traditional circuit breakers or fuses. Different from traditional fuses that must be replaced when they blow, polymer fuses are designed to open the circuit when a fault occurs and reset themselves when the fault is cleared.The RL3312-200-110-50-PTO is a resettable fuse that has a wide range of applications in electronics, power systems, automotive, and industrial electrical systems. It is also UL recognized and meets the requirements of IEC 60950-1. It is a self-recovering PTC that can provide overcurrent protection with remarkably fast response times and maximum currents up to 200A.This PTC device offers immense advantages compared to traditional fuse systems. It has a higher life cycle due to its repetitiveness in resetting, requires no maintenance, takes up less space, and has an improved surge protection. Its resettable feature reduces the need for purchasing replacement fuses and eliminates the danger associated with exposed live wiring.The RL3312-200-110-50-PTO also boasts a minimum self-restoration time of less than 10 ms and hold current of 110A. Its maximum circuit protection offers good current control which helps maintain a stable current. Additionally, it is a solid state device and, as such, has no moving parts and requires minimal attention to keep functioning correctly. This PTC device has a working principle that is based on the physical change of a polymer that, as with other positively temperature coefficient (PTC) materials, increases its resistance when its temperature rises. The device is designed to offer superior overload protection by being as responsive as possible. When a large current passes through the device, a significant amount of heat is consequently generated which triggers the PPTC device to act as a switch and open the circuit. As the current passes through the PTC device, it generates ohmic heat and eventually causes the PTC material’s temperature to rise above a certain threshold. When this temperature is reached, the device’s resistance increases and its current rating drops dramatically. The RL3312-200-110-50-PTO is designed primarily for use in general-purpose 12VDC circuits such as automotive electronics, power supplies, and small appliances. It can also be employed as an overcurrent protection element in a variety of other electrical applications. It has a reliable, neat external form factor and occupies minimal PCB space. The RL3312-200-110-50-PTO offers dependable, long-term circuit protection, customizable current ratings, and excellent resetting and self-restoration features. In conclusion, PTC resettable fuses are power management systems that provide electrical system protection from a variety of threats, including overcurrents, short circuits, and ground faults. The RL3312-200-110-50-PTO is the ideal choice for many applications due to its wide range of features and robust design. It offers reliable protection and resettable convenience all in a compact form factor. As such, the RL3312-200-110-50-PTO is a sensible option for most PTC fuse applications.
