In certain circumstances, high cable capacitance due to an excessive cable length could prevent an undervoltage release MN from dropping out resulting in safety issues. In case of a shunt trip MX, an untimely trip may occur due to capacitive current leak. To avoid these dysfunction due to cable capacitance C, the maximum cable length (L) is defined by the attached table for a 1.5 mm² cable.
