Abb tqdsb Service Barrier for Old Mod 1 Style Mslcs

Product Description

The ABB tqdsb is a service barrier designed for use with Old MOD 1-style Motor Starter Load Centers (MSLCs). Service barriers provide physical separation between energized bus components and service personnel, reducing arc flash exposure and accidental contact risk during panel maintenance. This part is a direct-fit accessory component intended for installation by licensed electricians or qualified panel technicians working on legacy ABB load center assemblies.

This service barrier is specifically suited for Old MOD 1-style MSLCs. It is intended for use in commercial and industrial electrical distribution applications where existing MOD 1-style load center enclosures require a compliant barrier during service or inspection procedures. It is not intended for use with newer MSLC configurations that differ from the MOD 1 form factor.

Key Features

• Designed specifically for Old MOD 1-style MSLC enclosures
• Provides physical separation between live bus components and service personnel
• Direct-fit accessory for legacy ABB load center configurations
• Supports safe service and inspection procedures in existing installations

Compatibility

Designed for use with Old MOD 1-style Motor Starter Load Centers (MSLCs). Not intended for use with newer or non-MOD 1 MSLC configurations.

Installation Notes

Installation should be performed by a licensed electrician familiar with NFPA 70 (NEC) requirements and arc flash safety procedures. De-energize the load center and follow lockout/tagout procedures before installing or removing any service barrier. Verify the existing enclosure matches the Old MOD 1-style form factor before installation. Do not modify the barrier or force it into enclosures for which it was not designed.
