WebRaychem Circuit Protection, a unit of Tyco Electronics Corporation, introduces the LVR series of PolySwitch® resettable devices. Designed for use in line voltage applications, the LVR series PPTC (poly-meric positive temperature coefficient) devices are rated at 240V AC, permitting maximum voltages of up to 265V AC, and Webbushing device uses the capacitance coupling of a specially constructed bushing of a circuit breaker or power transformer, as shown schematically in Fig. 2. Both of these relaying potential devices are called "Class A" devices.2 They are also sometimes called "In-phase" or "Resonant" devices3 for reasons that will be evident later.
