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.

Rated Voltage ~275 V AC (up to 385 V versions) – Designed for typical household and light commercial AC mains.
Low Let-Through Voltage (< 1.5 kV) – Limits the voltage that reaches connected equipment during a surge, reducing damage risk.
Compact DIN-Rail Mountable – Easy installation in electrical panels or distribution boards.
Flame-Retardant Durable Build – Made with robust materials for long-term reliability.
Auto-Reset After Surge – Resets itself after handling a surge event for continuous protection.
4-Pole Surge Protection Device (SPD) – Designed to protect three-phase AC systems plus neutral from voltage surges and transient over voltages.
High Surge Current Handling – Built to absorb surge currents (typically around 20 kA–40 kA depending on rating) to protect equipment from lightning strikes and switching transients.
Designed for Low-Voltage AC Networks – Works with 230/400 V AC at 50/60 Hz, making it suitable for residential, commercial, and light industrial electrical panels.
Fast Response & Low Let-Through Voltage – Quickly clamps and diverts excess surge energy to ground, reducing the risk of damage to sensitive electronics.
DIN-Rail Mountable – Compact, DIN-rail design for easy installation in distribution boards and sub-panels.
Thermal Disconnect Protection – Often includes thermal disconnection mechanisms for added safety if internal components overheat.
Visual Status Indicators – Many models use simple status windows/LEDs (green for normal, red for fault) to show device health and when replacement is needed.
2-Pole AC Circuit Breaker — Protects two lines in an AC electrical circuit.
Voltage Rating: Works at 230/400 V AC with 50/60 Hz frequency, suitable for standard power systems.
Current Ratings Available: From 6 A up to 63 A — choose based on your load requirement.
C-Type Trip Curve: Designed to trip on overloads and short circuits, and handle temporary current spikes (e.g., motors, lights).
