TOMZN 4P 63A 3Phase ChangeOver Switch Breaker-TO419G
The TOMZN TO419G 4P 63A Changeover Switch Breaker is a manual transfer isolating switch (MTS) designed for three‑phase AC power systems to safely switch between two power sources such as the utility grid and a backup generator or alternate supply. It features a 4‑pole configuration to separately handle all three phases plus neutral, ensuring balanced and reliable power transfer. Built with high‑temperature resistant, flame‑retardant plastic and compatible with standard 35 mm DIN‑rail installation, this switch simplifies manual power source control, prevents both sources from being connected at once (interlock mechanism), and enhances safety and continuity in residential and commercial power distribution applications.
