TO219G Manual Transfer Switch 63A 400V, 2Pole Interlock, Mini DIN Rail Description The TO219G is a compact manual transfer isolating switch rated 63A at 400V AC for reliable dual power source control. Its 2pole interlock design prevents simultaneous connection of two supplies and provides straightforward manual switching using a direct operation lever. Clearly marked terminals 1 through 8 simplify wiring and troubleshooting. The unit is DIN rail mountable and housed in a durable white enclosure sized for compact electrical panels. Key benefits Prevents supply crossconnection: the mechanical interlock blocks both sources from being connected at once, protecting equipment and simplifying safe switching procedures. Simple, dependable control: manual lever operation gives direct, intuitive switching for planned transfers and maintenance. Easy installation: compact mini form factor and DIN rail mounting save panel space; terminal markings 1 to 8 make wiring quick and clear. Versatile compatibility: rated for 400V AC and 50/60Hz, suitable for common residential and light commercial electrical systems. Stable, longterm fit: secure mounting design and robust housing support reliable performance in distribution panels. What makes it stand out Clear terminal identification reduces wiring errors and speeds installation. Twopole configuration handles both live conductors for full isolation during transfer. Compact ministyle housing fits tightly packed panels while providing solid mechanical support. Typical applications Home backup systems: manual switching between utility mains and a standby generator during outages. Small commercial premises: controlled transfer between primary supply and an alternate source such as a generator or inverter for planned maintenance. Temporary power installations: safe isolation and switching for construction site distribution or portable equipment setups.
