Model GCQ263/3P 3P63A dual power automatic transfer switch ATS switch Overview The GCQ263/3P 3P63A automatic transfer switch provides automatic switching between two power sources for 3pole circuits with a 63A rating. It is designed to maintain continuity of power for a range of electrical loads where timely source transfer is required. Key benefits Automatic source transfer reduces downtime by switching loads to the alternate supply when the primary supply fails or is outside acceptable parameters. Compact 3pole 63A form factor fits standard distribution panels and saves installation space. Simplifies system design by handling dual power management in a single device. Minimizes manual intervention, lowering operational overhead for routine transfers. Versatile compatibility with common 3phase power setups and typical auxiliary power sources. Main functions and attributes Function: Automatic transfer of load between two independent power sources for 3phase circuits. Model: GCQ263/3P, size designation 3P63A, rated current 63A. Compatibility: Intended for 3pole, 63 amp circuits and compatible with mains, standby generator, and inverter/UPS outputs of matching ratings. Performance: Designed to provide dependable switching behavior for critical and noncritical circuits where continuous power or controlled transfer is required. Installation: Suited for panel mounting in electrical distribution boards and control cabinets where a compact automatic transfer solution is needed. Practical use scenarios Residential backup power: Automatically switch household distribution circuits from utility supply to a standby generator during outages to keep essential systems running. Small commercial facilities: Maintain continuity for lighting, point of systems, and server closets by transferring loads to a backup source during utility interruptions. Light industrial and pump systems: Enable automatic source selection for motor circuits, pumps, and HVAC equipment where rapid and reliable transfer is needed to avoid process disruption. Why choose this model Clear sizing and rating make selection straightforward for 3phase systems up to 63A. The automatic transfer function reduces the need for manual switching and helps maintain operational continuity. Compact design integrates into existing panels and control setups without major layout changes. Technical reminder Verify that system voltage, frequency, and protective devices match the transfer switch rating and installation requirements before installation.
