Installation
The MCB-mounting (MCBM) version of SPM01 Miniature Energy Meter is specifically designed for seamless integration with miniature circuit breakers (MCBs). It ensures easy and efficient energy monitoring within existing electrical systems, delivering real-time data and precise measurement.

- Space saving: Installs easily into new or existing distribution boards without occupying DIN-rail space, perfect for crowded panels
- Real-time Monitoring: Measures Voltage, Current, Power and Power Factor in real-time to help users optimize energy usage.
- Large Aperture:  Supports cables up to 16mm² with a 9.6mm aperture, enabling measurement up to 63A.
- Precise Measurement: Delivers accurate active energy measurements with a tolerance of 1%, ensuring precise monitoring of energy consumption.
- Universal Zigbee 3.0 Support: Seamlessly integrates with standard Zigbee gateways and smart home hubs like Home Assistant, ensuring fast, local control without cloud dependency.

FAQ

Does SPM01 support bi-directional energy measurement?

Yes. The real energy flowing in the same direction as the energy flow arrow printed on the sensor housingis counted as forward energy.

Can I get a discount if I buy more units?

Yes. For bulk orders, you can refer to our Bulk Sales policy.

If you are interested in becoming a certified reseller, system integrator, or installer, you are also welcome to contact us directly via the email, WeChat, or WhatsApp details provided in the page footer.

How long does it take to ship after placing an order?

Orders are dispatched from our warehouse in Shanghai. Under normal conditions, delivery to most countries worldwide takes around 7–14 days.

What happens to energy data if the internet is disconnected?

The SPM01 MCBM continues to record cumulative energy consumption locally even when offline. No data is lost — once the internet connection is restored, the device automatically syncs the total accumulated energy to the cloud.

If the offline period is too long, the system may not display smaller time-scale energy data correctly.

Which circuit breakers are compatible with the SPM01 MCBM?

Currently, the manufacturer has officially verified compatibility with the Siemens 5SY and 5SL series. This verification includes comprehensive testing for wiring capacity, thermal performance, and mechanical fit.


The flexible version is recommended if you are unsure about MCB-mounting compatibility with your circuit breakers.


Can the SPM01 MCBM be flashed with custom firmware?

Technically yes. However, we strongly advise against doing so, as the device contains high-voltage circuits that pose safety risks during modification.

Does the SPM01 MCBM support 120V systems?

The Standard Zigbee version of SPM01 MCBM supports 120V systems and can be ordered directly.
