Leviton Telcom W463-S9 Surge Protective Device 63A

Product Description

The LEVITON TELCOM W463-S9 is an international-rated surge protective device designed to guard sensitive electrical equipment against transient voltage events. Rated at 63 amps and compatible with 208 to 250 volt systems, this unit is wired in a 4-pole, 5-wire configuration suitable for three-phase power distribution panels and industrial or commercial branch circuits. Electricians and electrical contractors install this device as part of a complete power protection strategy, particularly in facilities where international or multi-phase power infrastructure is present. The 4P5W configuration supports grounded three-phase applications where neutral and ground conductors are required.

This surge protective device is suited for commercial and light industrial environments operating on 208 to 250 volt, three-phase electrical systems. Typical installation scenarios include distribution panels, switchgear, and equipment protection applications where international wiring standards apply. It is sold as a single unit and is appropriate for use by licensed electricians working on multi-phase branch circuit protection projects.

Key Features

• 63-amp continuous current rating for robust surge protection capacity
• 208 to 250 volt operating range covering international and domestic multi-phase systems
• 4-pole, 5-wire configuration supports three-phase grounded neutral applications
• Single-unit packaging for straightforward procurement and installation

Compatibility

Designed as an OEM-style surge protective device for 4-pole, 5-wire three-phase electrical distribution systems operating in the 208 to 250 volt range.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lock out the circuit panel before beginning any wiring connections. Verify system voltage and phase configuration match the device ratings prior to installation. Do not exceed the 63-amp current rating of this device.
