Electrical Characteristics (at 20˚ C)
Product Notes:
1. A PTC device is not a fuse—it is a nonlinear thermistor that limits current. Under a fault condition all PTC devices go into a high resistance state but not open circuit so hazardous voltage
2. The devices are intended for protection against occasional overcurrent or overtemperature fault conditions and should not be used when repeated fault conditions or prolonged trip events

PolySwitch LVR Series
Resettable Protection Devices
LVR Line Voltage Series of PolySwitch devices for AC line voltage applications
Raychem Circuit Protection, a unit of
Tyco Electronics Corporation, introduces
the LVR series of PolySwitch
devices. Designed for use in line voltage
applications, the LVR series PPTC (poly-
meric positive temperature coefficient)
devices are rated at 240V
maximum voltages of up to 265V
are available in hold currents from 50 to
550mA.
The LVR series extends the proven
PolySwitch technology of resettable over-
current protection into higher voltage
applications. When installed in proximity
to potential heat generating components
such as magnetics, FETs, or power resis-
tors, the thermally active devices can help
protect against both overcurrent and
overtemperature faults in power sup-
plies, transformers and control circuits.
The properties of the LVR device can
offer distinct benefits in transformer
protection designs. The surface tem-
perature of the LVR device in the high
resistance state is well within the range
of most transformer winding insulation
ratings. This low temperature operation,
combined with small size, low resistance
and good thermal shock tolerance, can
allow the LVR device to be mounted in
direct contact with the transformer wind-
ings for a faster response to potential
fault conditions.
