Littelfuse LVR125S240 Line-Voltage-Rated PolySwitch

PolySwitch line-voltage-rated resettable devices protect electronic motors, transformers, and appliances from overcurrent and overtemperature faults. These polymeric positive temperature coefficient (PPTC) components are designed for line voltages up to 240V and current ratings up to 2A, offering fast trip times, low resistance, and reusability. They are RoHS and ELV compliant, suitable for industrial controls, lighting, medical equipment, and more. Unlike fuses, they reset automatically after fault removal, providing long lifespan, increased safety, and reduced maintenance costs in various high-voltage applications.
