Dual Power Automatic Transfer Switch (ATS) 2Pole 63A (2P63A) Keep critical circuits powered automatically when the main supply fails. This 2pole 63A ATS is designed for singlephase 110V or 220V systems and provides fast, reliable switching between your primary power and a backup source such as a generator, solar inverter, or battery backup. Why you need it Prevents service interruptions to lights, refrigeration, security systems, and essential equipment. Automatically restores power from a standby source when the grid fails, minimizing downtime and operational disruption. Offers a manual override for testing, maintenance, or controlled transfer. Key features Fast automatic transfer: switches to backup power in two seconds or less. Dual operation modes: fully automatic for hands protection and a manual override for direct control. Built for durability: fireresistant plastic housing, steel structural parts, and conductivity red copper contacts. Protection functions: builtin shortcircuit and overload protection to help safeguard connected equipment. Clear status indicators: bright lights show active power source and operational mode at a glance. Flexible mounting: wallmount for standard 63A models; compatible with DIN rail options for other models. Models available: 2pole 63A and 100A for singlephase circuits; 3pole and 4pole 63A for threephase systems. Technical compatibility 2pole 63A model suited for singlephase 110V or 220V residential and light commercial circuits. 3pole and 4pole 63A models designed for threephase commercial and industrial installations. Works with common backup sources such as portable or standby generators, inverter systems, and batterybased backups. Practical applications and scenarios Home backup: Automatically switch household circuits to a standby generator during a grid outage to keep lights, refrigeration, and security systems running. Small business or office: Maintain power to point of equipment, servers, and communication systems during brief or extended outages. Commercial or industrial sites: Use 3pole or 4pole models to protect machinery, elevator controls, and fire control systems where threephase power continuity is critical. Installation and use notes Designed for professional installation into existing electrical panels. Clear markings and simple wiring make integration straightforward. Use the manual override for scheduled testing or when performing maintenance on the backup source. Choose the correct pole and amp rating for the circuit and load requirements to ensure proper operation. What sets this ATS apart Rapid transfer speed reduces the risk of damage to sensitive electronics. Combination of automatic operation and manual control offers both convenience and flexibility. Durable construction and clear status indicators support reliable longterm use in residential, commercial, and industrial settings. Select the correct model for your system: 2pole 63A for singlephase 110V or 220V, 2pole 100A for higher singlephase loads, or 3pole and 4pole 63A for threephase installations.
