Weidmueller VARITECTOR PU AC surge protection

Thursday, 29 April, 2021 | Supplied by: Weidmuller Pty Ltd


The protection of sensitive electronic equipment against the harmful effects of lightning and surges is becoming more important as system complexities increase. Each critical area, from the incoming AC mains and distribution boards to final circuits and individual devices, can be protected using Weidmüller’s VARITECTOR range of surge protection devices.

The VARITECTOR PU AC family of mains surge protection devices provides Class II surge protection. It has an Imax of 50 kA (8/20 μS) and complies with IEC/EN 61643-11 as well as AS/NZS 1768: 2011.

Available in 1 ph, 1 ph+N, 3 ph and 3 ph+N formats, all MEN-connected domestic, commercial and industrial Class II installations can be protected.

To ensure sensitive equipment is protected over time, the VARITECTOR PU AC green flag indicator changes to red as the device nears its end-of-life signalling. Remote signalling is an option advising a replacement cartridge is required.

For further protection, versions are available with an additional yellow warning flag to indicate the partial end of life. This can be advantageous in areas of critical infrastructure where the need to always maintain protection is necessary. The replaceable plug-in cartridges are securely held in place with a positive locking lever. A high level of protection is afforded by a typical Up of 1500 V.
