All kinds of electric installations worldwide can be harmed by surges and lighting strikes. This results in faster degredation of components and in some cases instant failures leading to fires.
Fighting this surge protection can add to resilience of all kinds of electrical installations. For critical installations NFPA even demands the use of surge protection. One of them being all machines that have a safety circuit. According to NFPA 79, surge protection products must ensure voltage limitation according to the insulation coordination.
The VARITECTOR PU AC US series have the UL-Listed certification mark, which includes the requirements of NFPA 79. The product series is designed for North American grounding networks and is approved as type 1 in accordance with the highest UL classification.
The VPU AC US series enables safe operation with a short-circuit resistance (SCCR) of up to 200 kA.
The pluggable modules enable quick and cost-effective replacement of the arresters.
In addition to the requirements of UL 1449, the series is certified according to EN 61643-11.
