YCQR63 Dual Power Automatic Transfer Switch, 2P 63A Product overview A railmounted dual power automatic transfer switch designed for reliable automatic switching between two power sources. Model YCQR63 is a 2pole, 63 amp unit intended for compact electrical panels where automatic source selection and uninterrupted supply to critical circuits is required. Key benefits Automatic transfer between primary and secondary power sources to reduce downtime and remove the need for manual switching. Compact railmounted design saves panel space and integrates into existing control cabinets. 63 amp rated performance suitable for small to medium circuits that require dependable source selection. Simple selector function for clear source status and straightforward operation. Reduces the risk of human error during source changeover by making switching automatic and consistent. Essential features and specifications Model number: YCQR63 Poles: 2P configuration for singlephase branch circuits Rated current: 63A Mounting: railmounted for easy installation in standard electrical enclosures Function: dual power automatic transfer switch and electrical selector switch for automatic and manual source selection Compatibility: intended for integration with common distribution panels and backup power sources such as generators or alternate feeders Performance and suitability Designed to manage transfer between two separate AC power inputs, maintaining continuity for connected loads within the 63A rating. Built for frequent switching cycles typical in backup power applications where automatic selection is required. Compact 2pole layout keeps wiring organized and helps maintain panel space efficiency. Typical use scenarios Residential backup: automatic transfer of essential circuits to a standby generator when mains power fails. Small commercial or retail outlets: maintaining power to critical loads such as point of , lighting, and refrigeration during utility interruptions. Equipment control panels: automatic selection between primary supply and alternate feeder for pumps, HVAC control, or small machinery circuits. Installation and operation notes Intended for mounting on a rail inside a distribution cabinet. Follow local electrical codes and wiring practices during installation. Ensure connected loads do not exceed the 63A rating and that upstream protective devices are coordinated with the transfer switch. Use in applications requiring automatic or manual selection of two independent AC sources. Model YCQR63 provides a compact, straightforward solution for automatic dualsource switching in 2pole, 63 amp circuits, suitable for residential, commercial, and light industrial electrical panels.
