Schneider Electric H321AWK

The Heavy Duty Safety Switch is constructed to handle demanding applications, making it suitable for environments ranging from commercial to industrial settings. With a rated current of 30A and a NEMA 3R/12 protection degree, this fusible disconnect ensures robust performance. The switch operates at 240 VAC and 250 VDC, aligning with various operational requirements.

Designed with an emphasis on mechanical endurance, this safety switch exceeds the NEMA Type KS-1 and UL98 standards. The construction incorporates a substantial amount of copper in the current-carrying paths, which effectively reduces temperature rise, thereby extending the service life of the switch. In fact, the design life of this F-Series switch is at least three times more than the industry requirements.

This model is surface mounted with a durable galvannealed steel enclosure, and its dimensions are 14.6 inches in height, 6.63 inches in width, and 4.96 inches in depth. It supports H or K, R, J, or L fuses, with an acceptable AWG gauge range of AWG 12 to AWG 6 for aluminum wiring. The switch also features a short-circuit rating of 200kA at 240VAC, ensuring its reliability under fault conditions. Compliance with UL listed file E2875 standards underscores its suitability for safety-critical applications.
