                      Product Overview

                      RUEF400 is a RUEF series PolySwitch® Resettable radial leaded PPTC. It offers voltage rating of 30V and hold current of 4A.

                      • Resettable and single-use overcurrent device
                      • Operation temperature range from -40°C to 85°C

                      Warnings

                      This device is intended for protection against overcurrent or overtemperature fault conditions and should not be used when repeated fault conditions or prolonged trip events are anticipated.

                      Notes

                      Operation in circuits with a large inductance can generate circuit voltage (Ldi/dt) above rated voltage of device.
