Siemens HF327N Heavy Duty Safety Switch 800A 240V Fusible

Product Description

The SIEMENS HF327N is a heavy duty safety switch designed for use as a fusible disconnect in three-phase, four-wire electrical distribution systems rated at 240 volts and 800 amps. This type of disconnect provides a controlled means of isolating downstream equipment from the power supply, protecting circuits and personnel during maintenance or fault conditions. At 350.7 pounds and with a large enclosure footprint, the HF327N is built for industrial and commercial service entrance or feeder applications where high-ampacity switching and fused overcurrent protection are required. Licensed electricians handle installation and commissioning of this equipment.

The HF327N is suited for commercial and industrial facilities where three-phase power distribution requires a robust, lockable disconnect point. Typical applications include service entrance disconnects, motor feeder disconnects, and large HVAC equipment isolation points in buildings where 240-volt three-phase service is run. The large physical dimensions of this switch accommodate the substantial busbars and fuse blocks necessary for 800-amp service, making it appropriate for main distribution panels, mechanical rooms, and industrial process equipment installations.

Key Features

• Fusible disconnect design provides integrated overcurrent protection at the disconnect point
• Rated for 800 amps at 240 volts on a three-phase, four-wire configuration
• Heavy duty safety switch construction suitable for demanding commercial and industrial environments
• Large enclosure dimensions accommodate high-ampacity fuse blocks and busbars
• Lockable switch mechanism supports lockout/tagout safety procedures

Compatibility

Designed as an OEM-style heavy duty fusible safety switch for three-phase, four-wire 240-volt electrical distribution systems requiring an 800-amp disconnect. Consult applicable NEC requirements and local codes to confirm fitment for your specific application.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local ordinances. Verify that the upstream service is de-energized and properly locked out and tagged out before mounting, wiring, or servicing this switch. Due to the weight of approximately 350.7 pounds, proper rigging and mechanical assistance are required during installation. Always verify fuse type and ampere rating compatibility before energizing the completed installation.
