Given the cost of living crisis, I want to replace my night storage heater circuit breakers with smart 1P+N residual current circuit breakers providing overcurrent protection (RCBO) in one module.
There are a few listed on AliExpress but I’m hesitant to purchase anything which doesn’t conform to UK standards.
Has anyone found equivalent and compatible smart circuit breakers that include remote switch on/off and power monitoring?
No, I was warned not to replace my current circuit breakers with any DIN rail smart device - like the Shelly Pro units. I am still looking for a viable solution but I found a couple of potential options that added relays alongside the current circuit breakers so that I would continue to be protected.
Are you based in the UK? If so, did you have it professionally installed? I was warned against using any device that did not fully meet UK safety standards.
The mistake which you made was that you communicated your intention of removing a critical safety component - the MCB - from the circuit and replacing it with what is possibly a sub-standard and non-compliant component from AliExpress.
The only way to acceptably achieve this would be by installing a contactor device below the existing MCB and connecting this to a device such as a Shelly EM with a contractor interface.
That way the safety device remains in situ, but you obtain control of the circuit though a remotely switchable, purpose-designed controller.
I’ll just add that these modifications may not be considered “minor works” under UK legislation, so may not be authorised unless carried out by an electrician.
