Square D 9422TCF33 Cam Disconnect Switch 30A 600VAC

Product Description

The SQUARE D 9422TCF33 is a fused cam disconnect switch rated for 30 amps at 600 volts AC. It is a 3-pole, 3-wire open-enclosure switch designed to provide a manual means of disconnecting power in industrial and commercial electrical distribution systems. The switch carries a 7.5 horsepower rating at single-phase 208 volts and meets NEMA ratings 1, 12, 3R, 4, and 4X, making it suitable for a range of indoor and outdoor installation environments. Licensed electricians install this switch as part of branch circuit or equipment disconnect applications where code-required isolation of electrical loads is necessary.

This cam disconnect switch is used in commercial and light industrial settings where a reliable, fused disconnect point is required ahead of motors, HVAC equipment, or other electrical loads. The multi-NEMA-rated enclosure configuration makes it adaptable to dry indoor locations, dust-tight environments, and outdoor or corrosive-atmosphere applications. It is a common replacement or retrofit disconnect in mechanical rooms, rooftop equipment installations, and panel upgrade projects.

Compatibility

Designed as an OEM-style replacement or direct-install fused cam disconnect switch for 30-amp, 600-volt AC circuits requiring a 3-pole open-enclosure disconnect with NEMA 1, 12, 3R, 4, or 4X ratings.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the upstream circuit before handling any wiring or mounting the switch. Verify fuse ratings match the connected load requirements before energizing. The open enclosure configuration requires installation inside a suitable protective housing or panel where the NEMA rating of the installation environment applies.
