Description
Part of the legacy N-frame series, the NFJ634250NA is a 250A, three-pole molded case switch. It functions solely as a non-automatic disconnect, providing circuit isolation without overcurrent protection. This bolt-on device serves as an exact replacement for older Federal Pacific panelboards. It ensures a precise fit within existing enclosures without requiring retrofit adapters. Rated for an 18kA short-circuit withstand at 480VAC, the unit includes line and load lugs for quick integration.Specifications
