Description
The SONOFF Basic DIN Rail – Zigbee Version (BASIC-ZB1GSP) is a DIN rail-mounted Zigbee 3.0 smart switch from the SONOFF Basic Series, designed for residential and industrial energy management. Rated at 32A with a 7680W maximum load, it is ideal for EV chargers, water heaters, electric floor heating, heat pumps and other heavy-duty circuits.
It fits standard DIN rails in your distribution board with no drilling or modification, monitors voltage, current, power and energy in real time, and cuts the output automatically when your custom voltage, current or power limits are exceeded. Its double-pole switching disconnects both live and neutral for full electrical isolation, and it also works as a Zigbee router to extend your network.
Note: a Zigbee gateway is required (see "Works With" below). It must be installed by a qualified electrician behind a 32A circuit breaker, not directly on the grid, and is for single-phase use only. Energy monitoring is available only when the load neutral wire is connected to the device's output neutral terminal.
Key Features
- 32A / 7680W capacity for EV chargers, water heaters, floor heating and heat pumps
