The Eaton PRL1A Panelboard with Main Breaker SPD Surge Device combines a 100 A main breaker with an integrated surge protection device to shield downstream circuits from transient events. It is configured for 208T/120V, 3PH 4W service, supporting three‑phase, four‑wire operation (208V systems with 120V phase‑to‑neutral voltages). This panelboard provides centralized electrical distribution with built‑in SPD protection for enhanced equipment safety in commercial installations.
