FAQs
SPD100480Y3H is designed for left-terminal panel installations inside PRL-C configured panelboards. It wires to the main service with 50/60 Hz compatibility, and its internal mounting simplifies enclosure planning. The left-terminal layout reduces wiring complexity and potential termination strain, helping technicians commission systems faster while preserving UL compliance and field reliability.
Key ratings include 277/480V wye (4W+G), 100 kA per phase surge current, 200 kAIC short-circuit rating, and a 50/60 Hz frequency rating. Nominal discharge current is 20 kA, with L-N, L-G, and N-G paths rated at 320 V. These specs translate to robust transient protection for critical loads in industrial power networks.
Yes. The SPD100480Y3H is specifically designed for 277/480V wye configurations and is compatible with panelboards, including PRL-C setups. Its internal mounting and left-terminal wiring streamline integration in industrial facilities, while UL certifications confirm suitability for regulated environments and critical equipment protection.
SPD100480Y3H carries UL 1449, UL 1283, and UL Listed certifications. These indicate compliance with safety and performance standards for surge protection devices, reducing risk during installation and operation. For engineers, this translates to validated reliability in critical power feeds and a stronger basis for quality audits and compliance reporting.
Maintenance is simplified by features such as a surge counter and an audible alarm with a silence option, enabling quick fault verification and ongoing monitoring. The Form C relay supports integration with existing control logic, enabling proactive response.
