Product Description

The ABB thn3361 is a 30-amp, 3-pole, non-fusible heavy-duty safety switch rated for 600 volts AC. It is designed for use as a disconnect means in commercial and industrial power distribution systems where a reliable, code-compliant shutoff point is required. The switch ships in a NEMA 1 enclosure for indoor installations and is UL and cUL Listed. At 9 pounds and built to heavy-duty category standards, it provides a robust disconnect solution for motor loads up to 30 horsepower at 600 volts AC, 3-phase per NEC standard ratings. Licensed electricians install this switch as part of branch circuit or feeder disconnect applications.

The thn3361 is suited for commercial and industrial environments including manufacturing facilities, processing plants, and other indoor installations requiring a dependable non-fusible disconnect. It handles a wide range of motor horsepower ratings across multiple voltage configurations, making it a practical choice for 3-phase motor circuits up to 600 volts. Its 3-pole, 3-wire configuration covers standard industrial motor applications. Accepted under GSA compliance requirements, it is also eligible for use in federally procured projects.
