Model NLQ6125/4P power automatic transfer switch 125A 100A Size: 4P/63A Description A 4pole automatic transfer switch designed to manage safe and rapid changeover between two power sources. The NLQ6125/4P automates switching to reduce interruption time and improve conversion rates during source transfer for threephase systems with neutral. Key benefits Automatic and reliable source switching to minimize downtime during power interruptions. Supports circuits rated for 125A and 100A while fitting a 4P/63A installation footprint. Improves conversion rates between primary and standby sources for smoother transitions. Compact 4pole design suitable for threephase plus neutral installations. Clear function as an ATS simplifies integration into existing electrical distribution systems. Main features and attributes Function: Automatic transfer between two power sources with 4pole switching for threephase plus neutral. Compatibility: Intended for use with standard threephase distribution panels and common backup sources such as utility mains and standby generators. Size: 4P/63A, 4pole configuration to accommodate three phases and neutral in a single device. Rated currents: Applicable to systems using 125A or 100A rated circuits as indicated by the model designation. Performance: Designed for rapid switching to reduce interruption time and help maintain operational continuity. Typical applications Commercial buildings: Automatic transfer between utility power and standby generators to keep lighting, HVAC, and essential loads running during outages. Industrial environments: Protects production lines and machinery by transferring critical loads to backup power with minimal disruption. Temporary or remote sites: Reliable source switching for sites that depend on generator backup or portable power systems. Installation and use notes Intended for installation in electrical distribution panels by qualified electricians in accordance with local regulations. Verify that the device ratings match the system requirements, including current rating and pole configuration, before installation. Use with compatible upstream protection and control equipment as required by the electrical design. This NLQ6125/4P power automatic transfer switch provides a straightforward solution for automating power source changeover in threephase systems, combining a 4pole form factor with support for 125A and 100A circuits to address common backup power needs.
