Siemens HFB63 Replacement Fused Line Base 100A

Product Description

The SIEMENS HFB63 is a replacement fused line base rated at 100 amps, designed for use in electrical distribution and overcurrent protection applications. This line base serves as a mounting and connection point for fusible elements within a panel or disconnect assembly, providing a code-compliant method of protecting downstream circuits. Licensed electricians and electrical contractors install this component during new construction, panel upgrades, or service replacements where fused line protection is required. The HFB63 is built to integrate cleanly into the appropriate enclosure or switchboard assembly, supporting reliable overcurrent protection in both residential and light commercial settings.

The HFB63 is suited for electrical service panels and disconnect assemblies requiring fused line protection at 100 amps. It is typically installed in applications where the authority having jurisdiction or local code requires fused rather than breaker-style overcurrent protection. This component is appropriate for electricians working on service entrance equipment, feeder circuits, or branch-circuit distribution where a fused line base configuration is specified.

Key Features

• 100-amp rating for fused line overcurrent protection
• Replacement-grade design for restoring original fused line base functionality
• Compact form factor suited for panel and disconnect enclosure installation
• Compatible with standard fused line base configurations in electrical distribution assemblies

Compatibility

Designed as an OEM-style replacement fused line base for electrical distribution panels and disconnect assemblies requiring 100-amp fused line protection.

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 disconnect assembly before beginning any work. Verify that the replacement line base matches the original configuration and ampere rating before installation. Do not energize the assembly until all connections are secure and covers are properly reinstalled.
