PolySwitch LVR Devices

Littelfuse PolySwitch LVR devices help protect against damage caused by mechanical overloads, overheating, lost neutral, and other potentially harmful conditions

Image of Littelfuse's PolySwitch LVR DevicesThe Littelfuse PolySwitch LVR devices help protect against damage caused by mechanical overloads, overheating, lost neutral, and other potentially harmful conditions. The LVR line voltage product line of polymeric positive temperature coefficient (PPTC) devices includes components that are rated for line voltages of 120 VAC and 240 VAC. They help protect against damage caused by both over-current surges and over-temperature faults, offer low resistance, and are compatibly sized with fuse solutions. Unlike traditional fuses, PolySwitch devices do not require replacement after a fault event. After power has been removed and the fault condition eliminated, the circuit is restored to normal operating condition.

Available in Tape and Reel (TR-ND) and Cut Tape (CT-ND).
