ATS 4P 125A 3 Phase 4 Wire 230V MCB Type Dual Power Automatic Transfer Switch TOQ3-4P/125 PV City Power Generator

The TOQ3-125/4P is a 4-pole, 125A automatic transfer switch designed for 3-phase, 4-wire systems operating at 230V/400V. This MCB-type dual power switch enables seamless, automatic switching between two power sources — such as a photovoltaic (PV) system, city grid power, or a generator — ensuring an uninterrupted power supply to your critical loads. Built-in overcurrent protection adds an extra layer of safety, making it a reliable all-in-one solution for power management. The switch supports both Auto and Manual operating modes, giving you flexible control when needed. Its sealed protective enclosure makes it well-suited for demanding or outdoor installation environments. With a main circuit insulation voltage of AC400V, an impulse withstand voltage of 4kV, and short-circuit ratings of Icm 7.65kA and Icn 5kA, this unit is built to handle high-power applications. It operates across a frequency range of 50/60Hz and meets IEC/EN60947-6-1 standards, falling under ATSE Class CB and utilization category AC-33iB.
