NLQ4160/4 Dual Power Automatic Transfer Switch 160A 4P Key benefits Automatic, reliable transfer between two power sources to maintain continuous power to critical loads. Rated for 160 amp current and four pole operation, suitable for three phase systems with neutral. Simplifies power source management and reduces downtime by enabling fast, unattended switching. Compact footprint and straightforward integration into electrical distribution panels. What this switch does Monitors two incoming power sources and automatically switches the load to the available source when a failure or abnormal condition is detected. Four pole design provides coordinated switching of three phase conductors and the neutral conductor for safe, full system transfer. Manual override available for testing or maintenance operations. Key attributes Model: NLQ4160/4 Rated current: 160 amp Poles: 4P (four pole) Function: Dual power automatic transfer switching between primary and secondary power sources Compatibility: Designed for use with mains and backup power sources including generators and alternative utility feeds in three phase systems Performance: Supports continuous supply to connected loads up to the rated current, reducing interruption risk during power source transitions Construction: Engineered for installation in distribution panels and power control cabinets Practical applications Commercial buildings: Maintain power to lighting, HVAC, and critical office equipment when the main supply fails by switching to a standby generator. Small industrial sites: Protect production equipment and control systems by automatically transferring to a secondary supply during utility interruptions. Residential or multiunit properties with generator backup: Ensure uninterrupted power to essential circuits and common area systems. Why choose this model Clear specification with 160 amp capacity and four pole switching for three phase installations with neutral. Designed to integrate with common power distribution setups for reliable automatic transfer operation. Suitable for applications that require unattended switching and rapid restoration of power to critical loads. Installation and operation notes Install in accordance with local electrical codes and practices for transfer switches and protective devices. Verify that connected loads do not exceed the 160 amp rating and that wiring and protective devices are sized accordingly. Use manual transfer mode for commissioning and maintenance to confirm correct operation before automatic use.
