AC RCBO (Residual Current Circuit Breaker with Overload Protection), 1P+N (2 Pole) (NO), AC-3/AC-3e, < = 440V
EKL9-40 series Residual current circuit breakers with over current protection range provide a full protection to both the persons and the electrical appliances, as they are designed to automatically cutoff the power supply in case of overload, short-circuit and earth leakage.
They can be used as protection devices for 240V single-phase network.
Its maximum rated current reaches 40A, and the minimum leakage current has 4 options: 10mA, 30mA, 100mA, and 300mA.
The RCBO is equipped with an indication window and a reset button to distinguish between residual current trips (reset button pops up) and overload trips (indication window turns red).
The RCBO is in three or five DIN modules, so it is easier to install than the common solution MCB + add-on blocks.
