NLQ6250/2P Dual Power Automatic Transfer Switch 180A (also available in 200A, 225A, 250A) Key benefits Millisecondlevel switching to minimize interruption when switching between two power sources, improving system uptime and conversion reliability. Designed for integration with uninterruptible power supplies and backup generators to maintain continuous power to critical loads. Available rated currents let you choose the correct capacity for your installation: 180A, 200A, 225A, or 250A. Twopole (2P) configuration for reliable switching of two conductors with a compact footprint for panel mounting. What this product does Automatically senses loss or abnormality in the primary supply and transfers load to the secondary supply, then returns when the primary source is restored. Provides fast, repeatable operation to reduce chances of equipment reset or service disruption during source changeovers. Why customers need it Prevents costly downtime by ensuring fast, automatic transfer between main and backup power. Simplifies backup power management by automating transfers so operators do not need to intervene manually. Supports UPS integration to allow seamless power continuity for sensitive electronics and control systems.
