Single Phase 220V Automatic Transfer Switch 125A DIN Rail Dual Power Changeover for Generator Backup

Miniature Circuit Breakers TOQ5125/2P Overview These miniature circuit breakers serve as a dual power switch for switching between city power and a generator. They are designed to improve conversion rates and provide fast, compact switching without interrupting the load. Key benefits Fast, uninterrupted transfer: switching time under 8 ms minimizes disruption to connected equipment and reduces the risk of uncontrolled resets. Clear compatibility: intended specifically for use with city power and generator systems; not suitable for photovoltaic systems or inverters. Compact and robust construction: PC level housing offers a compact footprint suitable for standard distribution panels. Model options: available in three models to match installation requirements: TOQ5125/2P. Simple electrical interface: designed for L plus N 220240V 506Hz operation to match common single phase supplies. Features Dual power switch function for automatic or manual transfer between mains and generator. Switch time less than 8 ms to maintain continuous power to sensitive loads. No interrupt switching action to avoid momentary outages during transfer. PC level enclosure for durability and spaceefficient mounting in distribution boards. Clear model differentiation to select the appropriate device for current and system needs. Compatibility and limitations Use only with city mains and generator sources. Not compatible with photovoltaic systems or inverterbased power sources. Rated for operation with L plus N 220240V 506Hz. Typical applications Residential backup power: automatic or manual transfer between utility supply and home generator to maintain power to refrigeration, lighting, and control systems during outages. Small commercial premises: reliable switching for shops, offices, or small workshops that require fast restoration of power from a standby generator. Temporary power installations: event sites, construction temporary supply, and emergency setups where quick, compact switching between mains and generator is required. Installation notes Select the model that matches the installation current and switching requirements. Confirm the system supply is L plus N 220240V 506Hz and that the source types are city mains and generator only. Do not use for PV systems or inverterbased supplies. Models TOQ5125/2P This product is a focused solution for fast, compact dual power switching between city power and generator sources, designed to improve conversion rates and maintain continuity for connected loads.
