The AF49F is a panel board front trim from the A Series, sized at 49.500 in height by 20 in width, designed for flush mounting and enclosed to NEMA 1 standards.
Flush-mount installation means the trim sits level with the surrounding wall surface, typical for finished electrical rooms where protrusions are undesirable. NEMA 1 rating provides indoor protection against incidental contact with live components — no gasketing for moisture or dust, so keep it in a conditioned space.
Listed as current production, so the AF49F remains an active catalog item.
