Square D Masterpact NW16N 1600A

The Square D Masterpact NW16N 1600A is a high‑performance low‑voltage power circuit breaker from Schneider Electric’s acclaimed Masterpact NW series, engineered for demanding industrial and commercial electrical distribution systems. Designed for three‑phase service with a 1600 A frame rating, this breaker delivers dependable protection against electrical faults such as overloads, short‑circuits, and ground faults through integrated LSIG (Long‑Time, Short‑Time, Instantaneous, and Ground Fault) protective functions when paired with appropriate solid‑state trip units.

Built with a draw‑out configuration, the NW16N allows for convenient installation and removal within switchgear assemblies, reducing downtime during maintenance or service activities. Its robust construction and insulation make it suitable for low‑voltage applications up to 600 V AC, providing high interrupting capacity — typically up to 65 kA at 480 V — to safely interrupt fault currents and protect downstream equipment.

As part of the Masterpact line, this breaker offers flexibility in system coordination, enabling facility designers and electrical engineers to tailor protection settings to specific network requirements while ensuring system safety and continuity. Whether applied in industrial plants, commercial facilities, or critical infrastructure, the Masterpact NW16N combines durability, performance, and serviceability in a trusted power distribution solution.
