Diversitech dt-dds-30 Fusible Disconnect Switch 30A

Product Description

The DIVERSITECH dt-dds-30 is a 30-amp fusible disconnect switch designed for use in HVAC and refrigeration electrical circuits. A fusible disconnect switch serves as both a manual isolation point and an overcurrent protection device, allowing technicians to safely de-energize equipment before service and providing fuse-based fault protection. This type of switch is a standard requirement near outdoor condensing units and other HVAC equipment where a readily accessible disconnect is mandated by code. Licensed electricians and HVAC technicians are the primary installers.

This disconnect switch is suited for residential and light commercial HVAC installations, particularly as a load-side disconnect mounted near outdoor condensing units, heat pumps, and packaged rooftop systems. It provides a local means of disconnection as required by the National Electrical Code for motor-driven equipment. The 30-amp rating covers a wide range of single-phase residential and small commercial cooling equipment.

Key Features

• 30-amp fusible design provides both manual disconnect and overcurrent protection in one unit
• Suitable for outdoor HVAC condensing unit and heat pump installations
• Meets NEC requirements for a readily accessible disconnect means near HVAC equipment
• Accepts standard fuses for field-selectable overcurrent protection

Compatibility

Designed as an OEM-style replacement or new-installation fusible disconnect for residential and light commercial HVAC electrical circuits requiring a 30-amp rated disconnect point.

Installation Notes

Installation must be performed by a licensed electrician or qualified HVAC technician in accordance with the National Electrical Code (NEC) and all applicable local codes. Disconnect and lock out the main power supply before beginning any wiring work. The disconnect should be mounted in a readily accessible location within sight of the equipment it serves, as required by NEC Article 440. Do not exceed the 30-amp rating by installing fuses above the rated ampacity of the switch.
