The circuit breaker's rating current must be of 150 A, and the rated interrupting capacity selected must be the grater between 30 kA or the highest amount of current that could be available in the circuit. For monitoring the operation of the circuit breaker we recommend also using the alarm switch (AL). *2. The use of RCD with time-delay overcurrent protection is recommended upon to prevent unnecessary operation with surge current (Recommended sensitivity current rating: 30mA) *3. Install an MCCB for backup saving of class II surge protector. Refer to the data sheets of the class II surge protector for details. *4. If the service entrance switchgear and switchgear or protective device wiring distance is more than 10 m, install the class II surge protector on the power supply downstream. Class II surge protector is the combination of SPD3 and SPD4 or SPD5 SPD3 SPD3 SPD4 SPD5 *1, *2 (N) INSTALLATION EXAMPLES: Three phase/3-wire (delta connection) TT Systems Lightning is a natural phenomenon and this unit could receive surges exceeding the discharge withstand current rating. Then, there is a possibility of burning out and result in short-circuits because of exceeding the processing capacity. Upon to save a backup, the circuit breaker must be installed on the power supply side of the surge protector. Molded-case circuit breaker (MCCB) or residual current circuit breaker with overcurrent protection (RCD) can be used.
