Ex9LE residual current add-on blocks are suitable for domestic as well as industrial applications. They are based on electronic technology. It brings advantages of more accurate measuring of residual current and, as a consequence, reduction of unwanted tripping. (For possible use of this device, local legal requirements and conditions must be fulfi lled.) These devices also do not suff er with magnetization of the tripping unit. Thus, regular testing is not necessary to preserve function of the device.To fulfi ll predescribed mandatory testing given by the product standard, it is recommended to test the device regularly with a period of one year.
