TOMZN TQO5-100PV/4 Three-Phase Automatic Transfer Switch (ATS) – 100A
Power your three-phase electrical systems with confidence using the TOMZN TQO5-100PV/4 Three-Phase Automatic Transfer Switch (ATS).
This high-performance ATS automatically transfers load between Source A (Solar / PV / Inverter) and Source B (Grid / City Power) to ensure uninterrupted operation for industrial, commercial, and high-load applications.
Designed specifically for three-phase systems (R-S-T-N), it supports both automatic and manual control, includes clear source indicators, and is built from flame-retardant PC material. It meets international safety and performance standards, making it ideal for factories, shops, buildings, and large solar hybrid systems.
