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 dual power automatic transfer switch designed for 3-phase, 4-wire systems operating at 230V. This MCB-type ATS seamlessly switches between grid power and generator supply, ensuring continuous power delivery to critical loads without interruption. Built with a voltage relay-based control system, it automatically detects when the main power supply falls outside the normal operating range and initiates a transfer to the backup source. Rated for high-power contact loads, this switch is well-suited for demanding industrial and commercial applications. The sealed construction protects internal components from dust and moisture, supporting long-term reliable performance. It supports both automatic and manual operation modes, offering flexibility during maintenance or testing. The unit complies with IEC/EN60947-6-1 standards and carries CE certification. Key specifications include a rated voltage (Ue) of AC 400V, insulation voltage (Ui) of AC 400V, impulse withstand voltage (Uimp) of 4kV, and a frequency range of 50/60Hz. Short-circuit ratings are Icm: 7.65kA and Icn: 5kA, with a utilization category of AC-33iB and ATSE class CB.
