Product overview

TheEKR3L Smart RCBOnot only offers overload, short-circuit and residual current protection like conventional circuit breakers, but also the possibility of remote control and monitoring via theTuya appor aRS485 platform. It also features an automatic restart function to increase the reliability of the power supply in the circuit.

TheEKR3L Smart RCBOCombines the protective features of a traditional RCBO with modern smart home technology, offering users increased security, convenience, and control over their electrical systems. It is particularly useful for remote circuit management and can be integrated into more comprehensive smart home or building automation systems.
