® COMPACT NS circuit breaker: functions and characteristics General characteristics 044334 Suitability for isolation (positive contact indication) All COMPACT® NS circuit breakers and switches are suitable for isolation as defined in the IEC 947-2 Standard: ■ The isolation position corresponds to the O (OFF position); ■ The operating handle cannot indicate the OFF position unless the contacts E18569 E36863 are open; ■ Padlocks may not be installed unless the contacts are open.
® COMPACT NS circuit breaker: functions and characteristics E28801 General characteristics The limiting capacity of a circuit breaker is its ability to limit short-circuit currents. Circuit breaker current limiting capacity Exceptional current limiting capacity The exceptional limiting capacity of the COMPACT® NS line is due to the double break technique (very rapid natural repulsion of contacts and the appearance of two arc voltages in series with a very steep wavefront).

® COMPACT NS circuit breaker: supplementary technical information Trip curves Reflex tripping E28287 All COMPACT® NS circuit breakers and switches incorporate the exclusive reflex tripping system. This extremely simple system breaks very high fault currents by mechanically tripping the device via a "piston" actuated directly by the pressure produced in the breaking units resulting from a short circuit. For high short-circuit thermal withstand, this system provides a faster break.
