PPTC Line-Voltage-Rated Datasheet

PolySwitch™ Mains Rated LVR/LVB Series

TE PolySwitch LVR/LVB series 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. Typical application include: medical equipment, motors, fans and blowers, security and fire alarm systems, test and measurement equipment, transformers, USB hubs, ports and peripherals.

Current ratings from 50mA to 2A

Line voltage rating of 120VAC and 240VAC

Fast time-to-trip

Low resistance

RoHS compliant

PCB Wire Ended

All are UL, CSA, TUV approved

Protection of electrical and electronic circuits against excessive currents

Rapid switch from low resistance state to very high resistance with electrical overload or short circuit

Quick and automatic reset and return to low resistance state when fault condition corrected and power removed

Features:
