About this product
The Ogemray Smart Relay 25A is a "Powered by Shelly" device: Ogemray hardware running the genuine Shelly chip and firmware, controlled from the same Shelly app as the rest of the range. Its job is the loads a standard 16 A module can't touch: rated to 25 A / 6,000 W, it suits electric hot water systems, heat pump circuits and workshop equipment.
Power metering is built in, along with over-voltage protection with automatic recovery and over-power protection, so a fault trips the relay rather than cooking the circuit. 1 configurable input takes an external switch or timer signal.
It carries full Shelly smarts, local web interface, scripting, schedules, MQTT, and mounts on the wall with the included bracket rather than hiding in a wall box.
Model: Ogemray SW40 PbS
230 V fixed wiring at 25 A: licensed electrician only; typically replaces the hot water contactor arrangement.
