Electronic fuse protects 24V circuits
The all-new Waveguard provides industrial control and switching systems with fully reliable fault protection for switched-mode 24V DC power supplies
The all-new Weidmuller Waveguard provides industrial control and switching systems with fully reliable fault protection for switched-mode 24V DC power supplies; conventional automatic circuit breakers require too high a current to operate normally. As well as full, selective dynamic and static protection, the innovative Weidmuller Waveguard (patents applied for) offers many features to ensure its wide application potential.

Weidmuller's Waveguard comprises an electronic fuse using fast semiconductors and a factory-set trip current; it will trip in 3.5ms.
The highest permissible static value is 100% of the fuse's nominal current value (not the 250 to 1500% required by automatic circuit breakers).
To achieve a dynamic value trip, current spikes are fed to the load and activate the fuse when a short circuit is detected.
A conventional fuse is installed in series with the electronic fuse as added protection.
The Waveguard is housed in Weidmuller's Wavebox DIN-rail-mount housing.
The sophisticated features include a sliding switch to set and reset the fusing element with remote operation possible, six available connections including the NC contact for extra-low voltages, and LED indication of the fuse status.
Choices may be made of Weidmuller's proven screw clamp or non-screw tension clamp connections, a 24V DC primary branch circuit 0V potential and reset input and signal contact.
