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

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 suitable for line-voltage applications up to a continuous operating voltage of 240V

RoHS versions of all products are available.
