The GE DTHN3363J is a 3-pole, 3-wire, 100A non-fused disconnect switch rated at 600V AC, purpose-built for industrial and commercial power isolation applications. Its non-fused design makes it ideal for use where upstream overcurrent protection is already provided — such as motor disconnects, HVAC equipment isolation, and machinery lockout/tagout points. The DTHN series is a heavy-duty safety switch suited for use in demanding environments where reliable service entrance or branch-circuit disconnecting means are required under Canadian Electrical Code (CEC) guidelines.

A non-fused disconnect switch, like the GE DTHN3363J, simply provides a manual means of isolating power without any built-in overcurrent protection. A fused safety switch, by contrast, incorporates fuse holders to provide both disconnecting and overcurrent protection in one enclosure. The non-fused type is typically used downstream of an existing breaker or fuse, where upstream protection is already in place — for example, as a local disconnect for a motor or HVAC unit.
Yes. The DTHN3363J's 100A, 600V, 3-pole rating makes it well suited for use as a motor disconnect switch in industrial and commercial installations per CEC requirements, provided the motor's full-load current and horsepower rating fall within the switch's capacity. Always verify the specific motor data and installation requirements with a licensed electrician to ensure full CEC compliance.
