Abb tg4323 Fusible Safety Switch 100A 3-pole 240V

Product Description

The ABB tg4323 is a general duty fusible safety switch rated at 100 amps, 3-pole, 240 volts AC for use in residential and light commercial electrical distribution systems. It features a NEMA 1 indoor enclosure and supports 4-wire configurations with a copper and aluminum wire range of 10 to 1/0. Licensed electricians install this switch as a service entrance disconnect or branch circuit disconnect where a fusible, manually operated isolation point is required by code. UL Listed and GSA compliant, it meets standard NEC requirements for general duty applications.

This switch is suited for indoor residential and light commercial installations where a reliable fusible disconnect is needed. Typical applications include service entrance panels, motor disconnects, and feeder circuit isolation in buildings where a NEMA 1 enclosure rating is appropriate. The 3-pole configuration supports both single-phase and three-phase circuits up to 240 volts AC, as well as 250 volts DC. Horsepower ratings at 240 volts AC reach 7.5 HP single-phase and 15 HP three-phase under NEC standard fusing, and 15 HP single-phase and 30 HP three-phase under time-delay fusing.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the upstream supply and verify absence of voltage before mounting or wiring the switch. Confirm that conductor sizing, fuse type, and fuse ampere rating are appropriate for the connected load and circuit protection requirements. Do not install in wet, damp, or outdoor locations, as this enclosure is rated NEMA 1 for indoor use only.
