In many systems, a key feature for achieving safety is the use of circuit breakers that disconnect individual consumers or entire circuits in good time if there is a fault. This is not optimal, however, as shutdowns then occur without warning. With a new generation of measurement devices from Janitza for residual current monitoring, you can get a whole lot closer to fail-safe system safety.
