Abb TH3364 Fusible Safety Switch 200A 600V 3P Heavy Duty

Product Description

The ABB TH3364 is a heavy-duty fusible safety switch rated for 200 amps at 600 volts with a 3-pole configuration. It is housed in a NEMA 1 enclosure, making it suitable for general indoor installations in commercial and industrial facilities. The switch provides a reliable means of disconnecting power to electrical equipment and is designed to accept fuses for overcurrent protection. Licensed electricians install this type of switch as a service entrance disconnect, feeder disconnect, or motor circuit disconnect on distribution systems.

The TH3364 is designed for commercial and industrial applications where a robust, code-compliant disconnect is required. Typical installations include manufacturing facilities, processing plants, and commercial buildings where heavy-duty switching capacity is needed. The NEMA 1 enclosure is rated for clean, dry indoor environments. This switch handles the high fault currents and cycling demands found in industrial electrical systems, making it a standard choice for panel feeders and large motor disconnect applications.
