Abb THN3361R 30A 3-pole 600V Nema 3R Disconnect Switch

Product Description

The ABB THN3361R is a heavy-duty fusible disconnect switch rated for 30 amps, 3-pole configuration, and up to 600 volts. It is housed in a NEMA 3R enclosure, making it suitable for outdoor and rainproof installations. This switch provides a safe means of isolating electrical equipment from its power source, a standard requirement in commercial and industrial electrical systems. Licensed electricians install this type of disconnect during new construction, equipment changeouts, and service upgrades where code-required isolation points are needed.

This disconnect switch is used in applications where a weatherproof, lockable shutoff is required near HVAC equipment, motors, compressors, or other electrical loads. The NEMA 3R rating means the enclosure is designed to resist falling rain, sleet, and external ice formation, making it appropriate for rooftop, outdoor mechanical yard, and exterior wall-mount installations. The 3-pole design accommodates 3-phase power circuits up to 600 volts.

Key Features

• 30-amp continuous current rating
• 3-pole configuration for 3-phase circuit applications
• 600-volt maximum voltage rating
• NEMA 3R rainproof enclosure for outdoor use
• Heavy-duty construction for commercial and industrial service
• Fusible design allows overcurrent protection at the disconnect point

Compatibility

Designed as an OEM-style heavy-duty fusible disconnect switch for 3-phase electrical systems requiring a NEMA 3R-rated outdoor shutoff point at up to 600 volts and 30 amps.

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 the upstream circuit at the panel before mounting or wiring this disconnect. Verify that fuse sizing matches the load requirements and does not exceed the 30-amp rating of the switch. The enclosure must be mounted to maintain the NEMA 3R weatherproof integrity, with conduit entries properly sealed.
