Product details

Overview

The CH321N is a Schneider heavy-duty fusible safety switch rated 30 A at 240 VAC, 3 poles, 7.5 hp, in a NEMA 1 galvannealed steel enclosure with a factory-installed neutral. It accepts copper wire from AWG 14 to AWG 6 and aluminium from AWG 12 to AWG 6.

Compared to the HU361, the CH321N shares the same 30 A switching current and 3-pole single-throw configuration, but the HU361 is a non-fusible disconnect rated at 600 VAC and carries UL listing file E2875. The CH321N is fusible and rated at 240 VAC; choose the HU361 when the circuit requires a higher voltage rating and no fuse provision.
