Siemens introduces SENTRON ECPD, a groundbreaking Electronic Circuit Protection Device with cutting-edge electronic switching technology.
Up to 80 percent less space is required in the distribution board, compared to conventional solutions.
March 1, 2024 – Siemens has developed one of the world’s most innovative circuit protection devices with cutting-edge electronic switching technology. SENTRON ECPD (Electronic Circuit Protection Device) electronically switches off circuit faults if errors occur and, if necessary, trips the mechanical isolating contact downstream. Up to now, disconnection was handled purely through electro-mechanical elements. “This innovation offers a variety of benefits and has the potential to revolutionise today’s circuit protection world,” said Andreas Matthé, CEO of Electrical Products at Siemens Smart Infrastructure.
SENTRON ECPD enables completely new approaches in electrical planning, maximising safety, flexibility and delivering enormous space and energy savings compared to conventional solutions. “For the first time in the history of circuit protection, it is possible to benefit from several functionalities in one product and to activate them as required by the individual application or adapt them if needed. All of this combined with the solid-state switching technology enables up to a thousand times faster, wear-free switching,” added Matthé.
Circuit protection devices are central components of every electrical installation. If certain load current limits are exceeded, these devices disconnect the individual loads to protect people and systems from damage. In the event of a short circuit, for example, this type of disconnection occurs in commercially available circuit breakers in two to three milliseconds.
In comparison, SENTRON ECPD disconnects up to a thousand times faster, minimising the occurring short-circuit energy. This ensures maximum safety for people, systems, and electrical equipment. SENTRON ECPD also offers wear-free switching, which increases the service life of systems and reduces maintenance and repair costs. In addition, the integrated cyclical self-test (including the integrated RCD function) raises safety to an entirely new level not covered by current concepts.
