NQ454L2

Model NQ454L2 is a panelboard interior designed by Schneider Electric, primarily featuring main lugs. Constructed to handle a substantial rated current of 225A, it is intended for 3-phase electrical systems. The voltage rating encompasses both 240V AC and 48V DC, allowing for versatile applications in different environments.

This panelboard boasts a total of 54 pole spaces, maximizing distribution capabilities. The internal busbar material consists of aluminum, which promotes efficient conductivity and reduces potential overheating issues. Its wiring configuration incorporates a 4-wire setup, which is essential for balanced current distribution across the phases.

Compatibility with a variety of circuit breaker types—namely QOB, QOB-VH, and QHB—enhances its adaptability. The enclosure dimensions measure 38 inches in height and 20 inches in width. For NEMA 1 configurations, the enclosure depth is 5.75 inches, while NEMA 3R, 5, and 12 configurations require a 6.5-inch depth, allowing for usage in different environmental conditions.

Rated interrupted current levels for the NQ454L2 model can reach up to 10 kA, 22 kA, or 65 kA based on requirements. The terminal connections are made via lugs for line and neutral, accommodating wire sizes ranging from AWG 6 to 350 kcmil in aluminum. This design ensures reliable and effective electrical distribution for various applications.
