WEIDMÜLLER has released the WAVEGuard, an electronic fuse that remedies the inadequate trip capability of automatic circuit breakers.
It is composed of two fuse cartridges wired in series, a conventional safety fuse and an electronic fuse based on semiconductors. The nominal currents of 1.6A, 3.15A, 6.3A and 8A are achieved with a mains voltage of 24V dc.
It can selectively offer dynamic and static protection for electrical circuits supplied by switched-mode power supply units. The electronic fuse speeds up the troubleshooting process in the secondary circuit as well as reducing repair and corrective maintenance costs.
