Line Voltage Rated PolySwitch Resettable PTCs

Littelfuse PolySwitch LVR and LVB Line Voltage Rated Devices help protect electric motors and transformers used in commercial and home appliances from damage caused by mechanical overloads, overheating, stall, lost neutral, and other potentially harmful conditions. The LVR and LVB devices of polymeric positive temperature coefficient (PPTC) devices include components that are rated for line voltages of 120V_AC and 240V_AC, for up to 2A of operating current at +20°C. They help protect against damage caused by both overcurrent surges and overtemperature faults. They also offer low resistance and are compatibly sized with fuse solutions.
