Abb sbx7w75p3 Service Barrier XT7 750 Mcm

Product Description

The ABB sbx7w75p3 is a neXT service barrier designed for use with XT7 molded case circuit breakers rated at 750 MCM conductor capacity. This barrier provides physical separation between energized line-side terminals and the service entrance compartment, reducing arc flash exposure during inspection and maintenance work. It is a low-voltage electrical component installed by licensed electricians in panel and switchgear applications where safe service access is required by code.

This service barrier is suited for commercial and industrial electrical distribution systems where XT7 frame circuit breakers are installed. It is typically found in motor control centers, switchboards, and load centers requiring conductor sizes up to 750 MCM. The barrier supports compliance with arc flash mitigation and safe work practices in facilities where breakers remain energized during downstream service.

Key Features

• Designed for XT7 frame molded case circuit breakers
• Accommodates conductors up to 750 MCM
• Provides physical isolation of line-side terminals during service access
• Supports arc flash mitigation and safe electrical work practices
• OEM-matched fit for ABB Low Voltage Drives and GE Industrial Solutions XT7 series equipment

Compatibility

Designed for use with ABB XT7 frame molded case circuit breakers accommodating up to 750 MCM conductors. This part was previously distributed under the GE Industrial Solutions brand prior to the ABB acquisition of that product line.

Installation Notes

Installation should be performed by a qualified licensed electrician in accordance with NFPA 70 (NEC) and applicable local electrical codes. De-energize all downstream circuits and follow proper lockout/tagout procedures before accessing the breaker compartment. Verify the barrier seats fully and is secured before restoring power. Do not bypass or remove the barrier during live-panel service work.
