Compact NSX100 to 630 - Reflex Tripping

Tripping Curves

Compact NSX100 to 630 devices incorporate the exclusive re ex-tripping system.This system breaks very high fault currents.The device is mechanically tripped via a "piston" actuated directly by the pressure produced in the breaking units by the short-circuit.For high short-circuits, this system provides a faster break, thereby ensuring discrimination.Re ex-tripping curves are exclusively a function of the circuit-breaker rating.
