PolySwitch Resettable Devices
Line-Voltage-Rated Devices
PolySwitch 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 120V_AC
and 240V_AC, for up to 2A of operating current at 20°C.
They help protect against damage caused by both
overcurrent surges and overtemperature 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 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/LVRL series are for line voltage applications up to a continuous operating voltage of 240V_AC/120V_AC.
RoHS versions of all products are available.
