Protection of the circuit against short-circuit currents. Protection of the circuit against overload currents. Tripping is indicated by the centre position of the switching toggle and by a red mechanical indicator on the front of the unit. Test button for checking the tripping mechanism. Feeding from above or below. Snap action for low-wear switching of the contacts. Technology of the release unit - thermomagnetic. Additional bayable auxiliary modules (optional)- indication of switching position, fault trip, shunt trip, undervoltage trip, overvoltage trip. The NG125L circuit-breaker complies with the following standards- IEC/EN 60947-2, EAN: 3303430187660.
