4P 125A 3 Phase 4 Wire 230V MCB Type Dual Power Automatic Transfer Switch TOQ34P/125 Product overview A 4pole, MCB type automatic transfer switch for dual power systems. Rated 125 A for 3 phase 4 wire 230 V installations, model TOQ34P/125 provides automatic switching between two power sources, typically utility and generator, to maintain power continuity and protect circuits. Key benefits Automatic, unattended transfer: Detects loss or of the primary supply and switches to the secondary source to keep critical loads powered. Circuit protection integrated: MCB type switching combines transfer function with overcurrent interruption at the switch point, reducing the need for separate devices in the transfer path. Clear compatibility: Designed for 3 phase 4 wire 230 V systems with a maximum continuous current of 125 A per pole. Compact, serviceable design: 4pole configuration covers three phases plus neutral in a single unit for simplified wiring and smaller panel footprint. Predictable operation for planned and emergency use: Supports generator integration and automatic restoration to the primary supply when available. Important attributes Function: Dual power automatic transfer between two sources with MCB type switching. Electrical ratings: 4 poles, 125 A rating, for 3 phase 4 wire 230 V applications. Model: TOQ34P/125. Performance: Designed to switch power sources automatically to reduce interruption time for connected loads. Compatibility: Suited for integration with standard 3 phase generator sets and incoming mains in distribution panels and control systems. Typical applications Backup power for small commercial premises and retail outlets where automatic generator transfer is required to maintain operations. Construction sites and temporary power installations where a generator provides secondary supply and reliable switching is needed. Industrial control panels and machinery that require automatic changeover between utility and onsite generator for uninterrupted process power. Installation and use notes Intended for use in 3 phase 4 wire 230 V dual power systems with a maximum current of 125 A. Wiring and installation should follow local electrical codes and practices. Use appropriate upstream and downstream protection and coordination when integrating into distribution systems. Model reference: TOQ34P/125.
