Weidmüller VPU series surge protectors

Weidmüller has released a range of surge protection devices that meet the new global IEC standards while exceeding Australian standards.

The lightning and surge protection VPU series meets the current IEC 61643-11 and EN 61643-11 standards. While Australia’s prevailing standards may not be updated for another two years, users will now be able to ensure they meet any future engineering design requirements, saving both time and money.

The VPU range includes models for Category C3 to A for energy networks with about 200 variants available to ensure optimal choice for users. The range also includes products for photovoltaic facilities and wind power installations.

The range combines varistor and gas discharge technology to provide sustainable protection. This, together with the newly designed thermal fuse system, offers maximum reliability in lightning and surge voltage protection.

Each VPU module is easily and quickly pluggable. A mounting rail clip enables simple and fast assembly and removal, and without the need for tools. The devices can also be rotated 180º in the electrical/control cabinet to ensure flexibility during installation.

The units also feature a large, central status display window. If the flag in the status window changes from green to red it is no longer providing protection. The device can be replaced quickly because of the plug-in connectors and without the need to disconnect any wiring.

All modules are self-monitoring and an alarm function notifies users via a mechanical relay that the unit needs replacing.
