Reliable dual power automatic transfer switch for single phase 220V systems. This 2P 63A MCB type module automatically transfers load between two power sources to maintain continuous power to connected circuits. White finish and MCBstyle format make it suitable for electrical distribution panels and common residential or light commercial installations. Key benefits Automatic continuity: switches between primary and secondary power sources without manual intervention to minimize downtime. load capacity: 63 ampere rating supports moderately heavy single phase loads. Wide frequency compatibility: rated for 50/60Hz operation to match global power supplies. Easy integration: MCB type form factor fits standard distribution panel layouts for straightforward installation. Clear function: 2 pole design provides simultaneous switching of live and neutral for single phase systems. Main features and specifications Type: Dual power automatic transfer switch, MCB type Poles: 2P Current rating: 63A Rated voltage: 220V Rated frequency: 50/60Hz Color: White Function: Automatic transfer between two power sources for uninterrupted supply Compatibility: Designed for single phase 220V distribution circuits and common MCBstyle panels How it solves common problems Eliminates manual switching when utility power fails or is restored. Prevents accidental backfeed by ensuring a controlled transfer between sources. Reduces downtime for sensitive equipment by restoring power automatically when an alternate source is available. Practical use scenarios Home backup systems: Automatically switch essential circuits from grid power to a standby generator when utility power is interrupted. Small commercial or retail outlets: Maintain lighting and point of equipment by switching between mains and inverter or generator input. Remote site installations: Provide automatic source selection for equipment at cabins, kiosks, or temporary setups that rely on generator and mains combinations. Installation and performance notes Intended for use in single phase 220V distribution panels that accept MCB style modules. Ensure wiring and upstream protection are rated for 63A and match local electrical codes. Suitable for applications operating at either 50Hz or 60Hz. This automatic transfer switch provides a straightforward, reliable means to maintain electrical continuity between two power sources for single phase 220V systems, combining automatic operation with a standard MCB footprint for easy panel integration.
