400 Series TE5® Time Lag Subminiature Fuse


High breaking capacity fuse for safer, more robust applications now available at Digi-Key


Littelfuse/Wickmann 400 series TE5 subminiature time lag fuses are designed for overcurrent protection for a wide range of applications that may be susceptible to high inrush currents. It is 250V rated and designed in accordance to IEC 60127-3.

With a broad selection of current ratings ranging form 500mA to 6.3A, and breaking capacity of 130A, the 400 series offers features and options that are currently unmet by other manufacturers of this fuse type.

The high I2T values and breaking capacity of the series, combined with its vibration-resistant housing, enables safe operation under high fault currents and in harsh conditions.
