Technical data
Tripping curves: C curve - Overcurrent protection for any type of application.
Positive break indication - the green strip indicates that all the poles are open and allows work to be carried out
on the downstream circuit in complete safety.
Increase in the service life of the product: thanks to fast closure independent of the speed of action on the
handle.
Current limitation in the event of a fault: fast opening of the contacts prevents the loads from being destroyed in
the event of a short-circuit.
