Siemens FDFBER4 Ed Frame Circuit Breaker 4-pole

Product Description

The SIEMENS FDFBER4 is an ED frame molded case circuit breaker designed for electrical distribution panel applications. It is a 4-pole breaker built to interrupt fault currents and protect downstream wiring and equipment in commercial and industrial power distribution systems. The ED frame series is a recognized standard in switchboard and panelboard assemblies where reliable overcurrent protection and compact form factor are required. Licensed electricians and panel technicians are the primary installers of this device.

This breaker is suited for use in commercial and light industrial electrical distribution applications where a 4-pole molded case device is specified. The 4-pole configuration makes it appropriate for three-phase systems that also require a switched neutral, or for multi-wire branch circuit protection. It fits within ED frame panelboard and switchboard enclosures where FX-style bolt-on or plug-in mounting is used.

Key Features

• 4-pole configuration suitable for three-phase plus neutral distribution systems
• ED frame molded case construction for reliable fault interruption
• FX-style mounting compatible with standard ED frame enclosures and panelboards
• Compact footprint at 9 inches x 5 inches x 6 inches for space-efficient panel layouts
• Durable construction rated for demanding commercial and industrial environments

Compatibility

Designed as an OEM-style replacement or direct-fit breaker for ED frame panelboard and switchboard enclosures accepting 4-pole FX-style molded case circuit breakers.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the panelboard or switchboard fully before removing or installing any breaker. Verify that the enclosure and bus system are rated for the ED frame 4-pole form factor before mounting. Do not exceed the interrupting rating of the breaker for the available fault current at the point of installation.
