TOMZN 2P+2P MTS AC Dual Power Circuit Breaker MCB 50HZ/60HZ Change Over
The TOMZN 2P+2P AC Dual Power Manual Transfer Switch (MTS) is manual changeover device with integrated circuit breaker protection designed for two-path AC power systems. It allows you to safely switch between two AC power sources (such as utility/grid and a backup generator or inverter) when the main power fails, ensuring continuity of supply. The switch supports 230 V / 400 V AC at 50/60 Hz and offers overload, short-circuit, under-voltage, and phase-loss protection while preventing both sources from being connected at the same time. With simple manual operation and easy DIN-rail mounting, this MTS is ideal for homes, businesses, and critical power environments where manual control and reliable safety are essential.
