POLYSWITCH RESETTABLE
DEVICES
Line-Voltage-Rated Devices
PolySwitch line-voltage-rated (LVR) devices 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 line-voltage product line of polymeric positive
temperature coefficient (PPTC) devices includes
components that are rated for line voltages of 120VAC and
240VAC, for up to 2A of operating current at 20°C. They
help protect against damage caused by both overcurrent
surges and overtemperature faults. They also 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 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).
The PolySwitch LVR devices’ resettable functionality and latching attributes make them a reliable, cost-effective circuit
protection solution for both intermittent- and continuous-operation motor applications. Their low resistance, fast time-
to-trip, and low profile help circuit designers provide a safe and dependable product, comply with regulatory agency
requirements and reduce warranty repair costs.
LVR/LVB series are suitable for line-voltage applications up to a continuous operating voltage of 240VAC/120VAC.

Warning : Application Limitations for the LVR Product Line
Users should independently evaluate the suitability of and test each product selected for their own application.
This product should not be used in an application where the maximum interrupt voltage or maximum interrupt current can be exceeded in a fault condition.
Operation beyond the maximum ratings or improper use may result in device damage and possible electrical arcing and flame.
A PPTC device is not a fuse - it is a nonlinear thermistor that limits current. Under a fault condition all PPTC devices go into a high-resistance state but
do not open circuit, so hazardous voltage may be present at PPTC locations.
The devices are intended for protection against damage caused by occasional overcurrent or overtemperature fault conditions and should not be used when
repeated fault conditions or prolonged trip events are anticipated.
In most applications power must be removed and the fault condition cleared in order to reset a PPTC device; however under certain unusual conditions,
a PPTC device may automatically reset. PPTC devices should not be used in an application where an automatic reset could create a safety hazard, such
as garbage disposals and blenders. Appropriate qualification testing should be performed.
It is the responsibility of the user to determine the need for back-up or failsafe protection to prevent damage that may occur in the event of abnormal
function or failure of the PPTC device.
Operation in circuits with a large inductance can generate a circuit voltage (Ldi/dt) above the rated voltage of a PPTC device. This product should not be
used in an application where the maximum interrupt voltage or maximum interrupt current can be exceeded by inductive spikes.
Devices are not recommended for reflow soldering.
Device performance can be impacted negatively if devices are handled in a manner inconsistent with recommended electronic, thermal, or mechanical
procedures for electronic components.
*PPTC devices are not recommended for installation in applications where the device is constrained such that its PTC properties are inhibited, for example
in rigid potting materials or in rigid housings, which lack adequate clearance to accommodate device expansion.
*Contamination of the PPTC material with certain silicone-based oils or some aggressive solvents can adversely impact the performance of the devices.
*Does not apply for LVB devices.
