The Ditek D50-120/2083Y is a parallel-mounted surge protective device (SPD) for 120/208 VAC three-phase wye electrical services. It carries a UL 1449 listing as a Type 1 and Type 2 SPD and a 50 kA per-phase peak surge rating.
The D50-120/2083Y protects 120/208 VAC three-phase wye distribution panels and disconnects in commercial and industrial facilities. Therefore, it suits service-entrance and branch-panel applications on 4-wire-plus-ground systems.
First, individually fused suppression components handle each protection mode. As a result, a failure in one mode does not take the whole unit offline. In addition, a diagnostic LED indicates system power and SPD function. Furthermore, the compact form factor mounts close to the protected panel to keep lead lengths short — the single biggest factor in real-world surge performance.

Application Notes
First, keep the lead length between the panel and the SPD as short and straight as possible. As a result, the let-through voltage stays low. In addition, follow NEC and local AHJ requirements for parallel SPD installations. Also, verify the service configuration is 120/208 VAC three-phase wye — not delta — before installing.
