240V ELV Compliant, RoHS Compliant
The LVR series is the first PolySwitch device family
designed for use at line voltages of 120VAC to
240VAC. They may be used to help provide primary
side protection of chargers, power supplies, and con-
trol transformers in many industrial, commercial and
consumer applications. They are also appropriate to
help protect many 120VAC or 240VAC motors. In
addition, the LVR series is RoHS compliant.
