Weidmuller Varitector PU (VPU) AC US Surge Protection Devices
Weidmuller Varitector PU (VPU) AC US Series Surge Protection Devices deliver reliable safety and performance for energy systems. Certified to UL 1449 and IEC/EN 61643-11, they support global compliance while meeting rigorous North American standards. Designed for renewable energy systems, industrial machinery, process environments, and building infrastructure, the VPU AC US series combines strong performance with an excellent price-to-performance ratio. Tailored to North American grid configurations and grounding systems, these devices enhance system availability while providing robust protection for critical AC applications. As data centers are increasingly classified as critical infrastructure, surge protection has become essential. Even minor electrical disturbances can affect availability, SLA compliance, and operating costs.
The National Electrical Code (NEC) requires surge protective devices at service entrances for dwelling units, dormitories, and similar occupancies (Article 230.67), and also mandates surge protection for machinery safety circuits, fire pump controllers, emergency systems, and critical operations power systems. Weidmuller VPU AC US devices are designed to support these requirements, helping maintain compliance and protect essential installations.
