INTERRUTTORE DIFFERENZIALE magnetotermico A DUE POLI
CARATTERISTICHE TECNICHE
DESCRIPTION OF THE OPERATING SYSTEM »
RCBO JEL4A is with enhanced sensibility and fast – operating protection devices applicable in circuits with
harmonic or direct pulsating current component presence.
“Phase line + neutral + leakage “protection circuit breaker JEL4A is applied to the single-phase residential
circuit of 50Hz or 60Hz, rated voltage 230V, to protect leakage, civil electrical overload and short circuit. The
product is provided with many advantages such as small size, high breaking capacity, cutting off zero-line,
live line at the same time, and leakage protecting in the case of reverse wiring live line.

FUNCTIONS »
? Switching off heavy-loaded electrical circuits at short circuit or overload.
? Switching off heavy-loaded electrical circuits at insulation damage of the conductors to the consumers.
? Switching off heavy-loaded electrical circuits at presence of a person and animals under voltage.
? Switching off consumers at harmonic pres ence due to luminescent lights.
? Switching off consumers in DC circuits at fault currents presence.
? Used to protect not only particular consum ers/circuits, but also the whole panel.
? Remarkable with high reliability of current characteristics.
? Control: manual switching on and automatic switching off at failure in the insulation after the breaker.

MOUNTING »
? On DIN-rail
? Mounting position: vertical the residual current device is mounted in the distribution box, and
after the device the neutral conductor and the earthing conductor must not be connected
together. In order to work accurately, the device must have a three- or five-conductor grid with
separate operating neutral conductor (N) and separate protecting conductor (PE) (e.g., earthing
system TN-S or TT with three or five conductors).
