Monti Associates ma-60nf3 60A 3 Phase Non-fused Disconnect

Product Description

The MONTI ASSOCIATES ma-60nf3 is a non-fused disconnect switch rated for 60 amps at 240 volts AC on a 3-phase circuit. It is housed in a NEMA Type 3R enclosure, making it suitable for outdoor installation where rain, sleet, and external ice formation are concerns. The unit is UL Listed and CSA Listed, meeting standard safety certification requirements for electrical disconnect service. Licensed electricians install this type of disconnect as the locally required means of disconnect for HVAC equipment, compressors, and other motor loads.

This disconnect is designed for commercial and residential outdoor applications where a 3-phase power supply feeds equipment such as rooftop units, packaged HVAC systems, air compressors, or similar motor-driven loads. The 240-volt, 3-phase rating suits light commercial electrical systems where non-fused disconnects are specified because overcurrent protection is handled upstream at the panel. The NEMA 3R enclosure provides adequate weatherproof protection for exposed installations on building exteriors or equipment pads.

Key Features

• 60-amp continuous duty rating on a 3-phase circuit
• 240-volt AC rated for standard light commercial power supply
• NEMA Type 3R enclosure rated for outdoor use and weather exposure
• Non-fused design for use where upstream overcurrent protection is in place
• UL Listed and CSA Listed for compliance with standard electrical codes

Compatibility

Designed as an OEM-style replacement or direct-install non-fused disconnect for 3-phase, 240-volt AC electrical systems requiring a NEMA 3R outdoor disconnect enclosure.

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 making any wiring connections. The NEMA 3R enclosure must be mounted with the drain holes oriented correctly to prevent water accumulation inside the box. Verify that conductor sizing and termination methods meet NEC requirements for a 60-amp, 3-phase disconnect application.
