The Sentron ECPD (electronic circuit protection device) electronically switches off circuit faults if errors occur and, if necessary, trips the mechanical isolating contact downstream. Sentron ECPD disconnects up to a thousand times faster than the typical two to three milliseconds, minimizing the occurring short-circuit energy. It also offers wear-free switching and an integrated cyclical self-test (including the integrated RCD function). The device comes with a powerconfig app to adjust or add various functions. The device properties can also be adjusted as needed, e.g., rated current or tripping limits. The Sentron ECPD offers transparency on energy consumption in the final circuit through radio-based communication with the Sentron Powercenter 1000 and 3000 gateways. Additionally, it can be integrated into higher level systems using Modbus TCP.
