TOMZN 2P 63A ChangeOver Switch Breaker
The TOMZN TO219G 2P 63A Changeover Switch Breaker is a manual transfer switch combined with a circuit breaker designed for safe and reliable switching between two AC power sources (such as grid and backup generator or solar/inverter systems). Rated for 63 A and up to ~400 V AC, this dual‑function device lets you manually change power sources while also providing breaker protection. It features a 2‑pole design that isolates both live and neutral lines, an integrated isolating/interlock function for enhanced safety during maintenance, and a compact DIN‑rail mountable housing for easy installation in electrical panels. Ideal for residential, commercial, and industrial backup power setups, this switch helps maintain uninterrupted power supply when primary power fails.
