NLQ6250/4P millisecondlevel uninterruptible dual power automatic transfer switch, 250A inverter Size: 4P/160A Key benefits Fast, reliable transfer: Millisecondlevel switching between two power sources minimizes interruption to connected equipment and reduces downtime. Dual power automatic transfer: Automatically selects between main power and backup inverter or generator to maintain continuous supply. current capacity: Rated for 250A operation to handle heavy loads while deployed in a 4pole configuration. Improves conversion rates: Designed to streamline source changeovers and improve overall power conversion performance for inverter systems. Clear sizing and compatibility: Listed as Size 4P/160A while carrying model designation NLQ6250/4P and a 250A switching rating for system planning and integration. Function and performance Automatic transfer operation monitors both input sources and switches to the available supply within milliseconds to avoid equipment reset or data loss. Intended for use with inverter systems and conventional mains or generator inputs to create an uninterruptible dual power solution. 4pole switching provides comprehensive control for threephase systems plus neutral, supporting balanced load transfer and simplified wiring layout. Compatibility and installation Model NLQ6250/4P fits installations that require a 4pole automatic transfer switch and 250A switching capability. Size 4P/160A specification allows engineers and electricians to confirm mechanical and electrical compatibility with switchboards and panels. Suitable for integration with inverters, diesel generators, and mains distribution systems where automatic, speed transfer is required. Typical applications Small to medium data rooms and IT closets where millisecond switching protects servers and networking equipment from interruption. Commercial and light industrial sites that use inverter systems and need automatic switching between utility and backup generation to keep production equipment running. Residential or multiunit buildings with inverterbased backup power setups to maintain critical circuits during outages. Why choose this model Model NLQ6250/4P combines millisecondlevel switching and dual power automatic transfer capability in a 4pole, 250Arated device, improving conversion performance for inverterbased systems and reducing service interruption risk.
