Shelly Pro 4CB C16A

Took me about twenty minutes to wire into my existing DIN rail setup, and the compact footprint left plenty of room for other breakers. The C16A rating handles my workshop circuits without a hint of heat, and the switching feels reassuringly solid.

The relays snap in place with a satisfying click, and the compact footprint made it easy to fit into my crowded panel. Switched over my garage lighting and it’s been rock-solid for a week straight.

Took me about 20 minutes to wire it into the DIN rail, and the compact size left plenty of room in the cabinet. The C16A rating gives me real peace of mind for the heavier loads. Solid build, zero issues so far.
