TOMZN 2P 63A 230V Single Phase MCB Type Dual Power Automatic Transfer Switch – ATS
The 2P 63A Single Phase Automatic Transfer Switch (ATS) ensures that your critical loads remain powered by automatically switching between Normal and Reserve power sources when one fails.
This terminal-type ATS is ideal for AC 230V, 50/60Hz, up to 63A, and complies with IEC60947-6-1 & GB/T14048.11. The switch defaults to Normal power when available, and switches to Reserve power only when Normal is unavailable.
– Power is briefly interrupted during switching (Switch time <4s).
– This switch cannot start or stop a generator – it only switches between available power sources.
