Abb tgn3326a1 Non-fusible Safety Switch 600A 3P 240V

Product Description

The ABB tgn3326a1 is a non-fusible, general-duty safety switch rated for 600 amps, 3 poles, and 240 volts, housed in a NEMA 1 enclosure. Safety switches of this type serve as a manual disconnect point in electrical distribution systems, allowing technicians to isolate downstream equipment for safe service or shutdown. The non-fusible design means overcurrent protection is handled upstream by a separately installed protective device. Licensed electricians install this switch in commercial and light industrial settings where a reliable, code-compliant disconnect is required.

This switch is suited for use as a service entrance disconnect or branch-circuit isolator in systems operating at up to 240 volts AC. The NEMA 1 enclosure rating makes it appropriate for indoor installations in dry, non-hazardous locations. At 600 amps and 3 poles, it handles substantial load capacity, making it a common choice for motor disconnects, HVAC equipment feeds, and large electrical distribution panels in commercial buildings.

Key Features

• 600 amp continuous current rating for high-load applications
• 3-pole configuration for three-phase or single-phase service disconnect use
• 240 volt AC rating suitable for standard commercial distribution voltages
• Non-fusible design isolates equipment without internal fuse protection
• NEMA 1 indoor enclosure protects internal components in dry interior environments

Compatibility

Designed as an OEM-style replacement or direct-install non-fusible general-duty safety switch for indoor electrical distribution systems requiring a 600 amp, 3-pole, 240 volt disconnect point.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lockout/tagout the upstream supply before mounting or wiring the switch. The NEMA 1 enclosure is rated for indoor dry locations only and must not be installed in wet, damp, or outdoor environments. Verify that all conductor sizing and termination torque requirements conform to the NEC and the authority having jurisdiction before energizing.
