Abb TNIA63 Fusible Neutral 100 Amp

Product Description

The ABB TNIA63 is a 100-amp fusible neutral designed for use in electrical panelboards and switchboard assemblies. It provides a code-compliant method of protecting the neutral conductor in a multi-wire branch circuit or service entrance application. The fusible neutral insert allows the neutral to be opened and tested independently from the ungrounded conductors, a requirement in certain NEC-compliant installations. Licensed electricians install this component during new construction or service upgrades where the authority having jurisdiction requires a fusible neutral arrangement.

The TNIA63 is used in commercial and residential electrical distribution equipment where a 100-amp fusible neutral is specified. It is typically installed in conjunction with compatible ABB panelboard neutral assemblies and service entrance equipment. This part is suited for installations where NEC provisions require the neutral to carry overcurrent protection matching the ungrounded conductors in the circuit.

Key Features

• 100-amp fusible neutral rating for overcurrent protection of neutral conductors
• Designed for installation in panelboards and switchboard neutral assemblies
• Supports NEC-compliant fusible neutral configurations in multi-wire and service entrance circuits
• Allows independent opening and testing of the neutral conductor

Compatibility

Designed as an OEM-style fusible neutral component for use in ABB electrical panelboard and switchboard assemblies requiring a 100-amp fusible neutral.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the panel or switchboard completely before handling any neutral components. Verify that the fusible neutral rating matches the overcurrent protective devices on the ungrounded conductors before installation. Do not install or remove the fusible neutral under load.
