LVR Line-Voltage-Rated Resettable Fuses

Littelfuse LVR Line-Voltage-Rated Resettable Fuses 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 product line of polymeric positive temperature coefficient (PPTC) devices includes 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 over temperature faults, offer low resistance, and are compatible with fuse solutions. Unlike traditional fuses, these do not require replacement after a fault event. After power has been removed and the overcurrent condition eliminated, the circuit is restored to normal operating condition. Compared to bimetal breakers, they offer greater flexibility, longer lifespan, and lower electromagnetic interference (EMI). LVR devices resettable functionality and latching attributes make them a reliable, cost-effective circuit protection solution for both intermittent and continuous operation motor applications.
