The LVR055K is a 0.55A PolySwitch Resettable Device that offers low resistance and is compatibly sized with fuse solutions. It helps to protect electric motors and transformers from damage caused by mechanical overloads, overheating, stall, lost neutral and other potentially harmful conditions. This LVR series line-voltage product line of polymeric positive temperature coefficient (PPTC) device includes components that are rated for line voltage of 120 and 240VAC, for up to 2A of operating current at 20°C. Helps to protect against damage caused by both over-current surges and over-temperature faults. Unlike traditional fuses, PolySwitch device do not require replacement after a fault event. After power has been removed and the over-current condition eliminated, the circuit is restored to normal operating condition. Compared to bimetal breaker, This LVR device offers greater flexibility, longer lifespan and lower electromagnetic interference (EMI).
