NLQ6250/2P Dual Power Automatic Transfer Switch, 200A Also available in 225A and 250A ratings Key benefits Millisecond level switching to maintain continuous supply when switching between two power sources. Reduces downtime and interruption of sensitive equipment by providing fast automatic transfer. Simplifies backup power management by automating changeover between utility and alternate source. Available current ratings (200A, 225A, 250A) let you match capacity to your installation requirements. What it does Automatic transfer switch for dual power systems that detects supply loss or failure and transfers load to the alternate source within milliseconds. Designed for integration with mains, generator, and UPS systems to enable uninterrupted operation of connected loads. 2 pole configuration suitable for single phase or twowire control circuits where a twopole transfer is required. Key attributes Model: NLQ6250/2P 200A (variants: NLQ6250/2P at 225A and 250A). Size and configuration: 2P compact form factor for panel or rack mounting in electrical distribution setups. Performance: millisecond switching response to minimize voltage interruption and improve conversion rates between sources. Construction: industrialgrade housing and components designed for routine electrical distribution use and long service cycles. Compatibility: intended for use with generators, utility mains, uninterruptible power supplies, and power distribution panels of matching voltage and current specifications. How it solves common problems Eliminates manual switching and the resulting response delay during source failure. Reduces risk of equipment trips or data loss caused by brief outages or slow transfers. Matches capacity needs through selectable rated models to avoid oversizing or undersizing the transfer switch. Typical applications Data centers and server rooms where fast transfer is needed to protect IT equipment and maintain uptime. Commercial buildings and offices using generator backup or UPS systems for critical loads and commonarea systems. Industrial control panels and production lines that require rapid switch to backup power to prevent process interruptions. Installation and selection notes Choose the model rated for the expected continuous load current: 200A, 225A, or 250A. Verify voltage, frequency, and grounding compatibility with the site power systems and connected equipment. Mount in an appropriate electrical enclosure with access for wiring, control logic, and maintenance. Summary NLQ6250/2P dual power automatic transfer switches provide millisecondlevel transfer performance in a compact 2P design. Available in 200A, 225A, and 250A ratings, they offer a practical solution for maintaining continuous power to sensitive loads and streamlining backup power operations.
