2920L PolySwitch® Resettable Fuses

Littelfuse 2920L PolySwitch® Resettable Fuses provide overcurrent protection for medium-voltage applications that require resettable protection. These polymeric positive temperature coefficient (PPTC) devices feature high voltage, a low profile, and a fast response to fault currents. The 2920L resettable fuses operate at -40°C to +85°C temperature range. Typical applications include IEEE 1394 port protection, powered ethernet port protection (IEEE 802.3 af), automotive electronic control module protection and low-voltage telecom equipment protection.
