TOMZN TOQ3 4P 125A Automatic Transfer Switch ATS | 3 Phase Dual Power 220V/400V

TOMZN TOQ3 4P 125A Automatic Transfer Switch (ATS) is a high-capacity dual-power automatic changeover switch designed for 3-phase electrical systems. It automatically switches the load from the Normal Power Source to the Reserve/Backup Power Source when the normal supply fails, helping maintain power to connected loads.

The TOQ3-4P/125A supports 3-phase 4-wire systems, with a rated current of 125A and AC 50/60Hz operation. It can be used for applications where automatic changeover between two available power sources is required, including backup power and generator-based systems

Important Note:

TOQ3 125A model does not provide built-in overcurrent or short-circuit protection. Appropriate external protection, such as an MCB/MCCB, should be used in accordance with the electrical installation requirements. Also, the ATS transfers between existing power sources; it does not start or stop a generator itself. Power interruption can occur during the switching process.
