Mars mars-83321 Non-fused Disconnect 60A 3 Phase

Product Description

The MARS mars-83321 is a 60-amp, non-fused, 3-pole disconnect switch designed for safe isolation of electrical loads in commercial and industrial applications. Rated up to 600 volts, it provides a reliable means of de-energizing equipment during service, maintenance, or emergency shutoff. The 833 Series is available in general duty and heavy duty configurations, covering a range from 30 to 100 amps and 120 to 600 volts. Licensed electricians and HVAC technicians install this type of disconnect to meet NEC requirements for motor disconnect means at or near the equipment served.

This disconnect switch is suited for 3-phase electrical systems commonly found in commercial HVAC equipment, refrigeration units, air handlers, and industrial machinery. Its non-fused design means overcurrent protection must be provided upstream by a properly rated fuse or breaker in the panel. It is typically mounted in an accessible location within sight of the equipment it serves, per NEC guidelines for disconnect means.

Key Features

• 60-amp continuous current rating for 3-phase loads
• Non-fused design — upstream overcurrent protection required
• 3-pole configuration for 3-phase circuit isolation
• Rated for use up to 600 volts
• Part of the 833 Series, available in general duty and heavy duty types
• Current range within the series: 30 to 100 amps

Compatibility

Designed as an OEM-style replacement or new-installation disconnect for 3-phase electrical systems requiring a non-fused 60-amp isolation switch rated to 600 volts.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize the upstream circuit at the panel and verify zero voltage with a meter before handling any wiring. Mount the disconnect in a readily accessible location within sight of the equipment it controls. Ensure the upstream overcurrent device is properly sized, as this unit contains no internal fusing.
