2920L PolySwitch® Resettable Fuses

Littelfuse 2920L PolySwitch® Resettable Fuses provide overcurrent protection for medium voltage applications that desire resettable protection. These Polymeric Positive Temperature Coefficient (PPTC) devices feature high voltage, low profile, and 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.
