TOMZN 1P 63A ChangeOver Switch Breaker-TO119G
The TOMZN TO119G 1P 63A ChangeOver Switch Breaker is a manual transfer switch with built‑in breaker protection designed to safely control and alternate between two AC power sources (such as grid and generator or backup supply) for single‑phase systems. It ensures continuous power availability by letting the user manually switch to a secondary source whenever the primary supply fails, while also providing circuit protection. Made from flame‑retardant plastic and featuring a mechanical interlock to prevent simultaneous connection of both sources, it is easy to install on a 35 mm DIN rail and offers dependable performance for homes, offices, shops, and light industrial applications.
