D325N

The D325N from Schneider Electric is a robust general-duty safety switch categorized as fusible, structured for enhanced flexibility in electrical installations. It can withstand a significant short-circuit current rating of 100 kA, depending on the specific fuse type used. This switch is capable of supporting motor power ratings of 50 hp at 240V AC, as well as 125 hp at 240V AC for 3-phase motors, demonstrating its utility in demanding scenarios.

Weighing 114.6 lb (52 kg), this safety switch has dimensions of 8.88 inches in width, 24.88 inches in depth, and a height of 45.12 inches, making it suitable for various mounting requirements. The unit is designed for surface mounting, ensuring convenient installation in spaces with limited space.

Rated at 400 amperes, the D325N switch is versatile in its use of wire sizes, with an acceptable range from AWG 1/0 to 600 kcmil, and is compatible with both aluminum and copper wiring. The tightening torque specification is 340 lbf.in (38.4 N.m), ensuring secure connections. Notably, it features an NEMA 1 enclosure rating, making it ideal for indoor use. The D325N has factory-installed neutral connection capabilities and supports a 4-wire configuration consisting of three phases and ground, alongside three poles for effective circuit management. Furthermore, it is designed to accept various fuse types: H, K, J, or R, expanding its flexibility in circuit protection.
