The H366R from Schneider Electric’s Square D series operates as a single-throw safety switch, engineered for demanding applications. Rated for a maximum current of 600 amperes, it can handle voltages up to 600 volts AC or DC. This unit features a three-pole configuration that promotes effective control of electrical circuits.
Fused isolation is incorporated into the design, ensuring reliable disconnection while using compatible fuses of types H, K, R, or J. Its short-circuit capacity stands at 10 kA with H/K fuses, and up to 200 kA for R/J fuses, making it robust against overloads. The switch's design excludes a neutral assembly, focusing exclusively on high-capacity operations.
The enclosure is rated NEMA 3R, offering ample weather resistance due to its construction from galvanized steel. This quality ensures durability in outdoor settings. The mounting method is surface-mounted, allowing for simplified installation in various environments.
For electrical connections, the H366R employs lug-based terminal connections and supports a 3-wire wiring scheme. The conductor size ranges from 3/0 AWG to 500 kcmil for both copper and aluminum materials, accommodating a wide variety of wiring configurations suitable for heavy-duty applications. The maximum motor power rating for this switch reaches up to 500 HP at 600V AC in a three-phase system.
