DIN Rail Automatic Transfer Switch

Manually switching between solar and grid power when the sun drops or supply cuts out means someone has to be there to flip it — this DIN Rail Automatic Transfer Switch handles that changeover on its own. Wired between a solar input and city power supply, the switch monitors both sources and automatically transfers the load to whichever is available, keeping connected circuits running without manual intervention. A manual/auto toggle switch and status indicator lights let you override the automatic behaviour or check which source is currently active at a glance, while DIN rail mounting keeps installation straightforward inside a standard distribution board. Key Features Automatic solar-to-grid changeover → Switches the load between solar and city power automatically as availability changes Manual/Auto selector switch → Override automatic operation when manual control is needed Status indicator lights (A/B) → Shows at a glance which power source is currently active 125A rated working current, 220V AC → Sized for standard single-phase residential or small commercial loads 690V AC insulation voltage, 8kV impact resistance → Built to the printed insulation and impact-resistance ratings on the unit DIN rail mounting → Fits directly into a standard distribution board without extra brackets Specifications Spec Detail Rated working current 125A Rated working voltage 220V AC Insulation voltage 690V AC Impact resistant voltage 8kV Frequency 50/60Hz Standard IEC 60947-6-1 Mounting DIN rail, 2-pole Poles/terminals R, N terminals; passive input/output terminal blocks What's in the Box 1 x DIN Rail Automatic Transfer Switch
