The circuit breaker or the fuse as disconnectors must be installed. Molded-case circuit breaker (MB) or residual current circuit breaker with overcurrent protection (RD) can be used. The rated interrupting capacity of the circuit breaker must be greater than the highest amount of current that could be available in the circuit. Install MB (rated current 0 0A) that has element for each phase. Or RD with protection from nuisance tripping against transit voltages type or time-delay overcurrent protection type is recommended. Recommended sensitivity current rating: 0mA *. able length between the branch point and the earthing: 0.5 meters or less recommended *. The protected 's metal enclosure must be cross-wired to the earth terminal of the MAT. If the protected has no earth terminal, earth only the MAT. *4. In order to protect an electronic circuit such as measuring equipment or communication equipment, we recommend to use surge protectors which have serial impedance incorporated such as M-System's models MAX, MMA, MAH.

For TT system, in order to ensure safe failure mode at TOV due to earth fault on high-voltage systems, connect between terminal and of the MAT. *. For TT system, in order to ensure safe failure mode at TOV due to earth fault on high-voltage systems, install a four-pole (three-pole plus neutral) circuit breaker. *. For single-phase/-wire system, connect lines to terminal and of the MAT. For single-phase/-wire system, connect the neutral line to terminal of the MAT. ALARM OUTPUT When the alarm output is to be transmitted remotely via outdoor cables, a surge protector for the signal line is required. MAT SIFIATIOS ES-864 Rev.0 Page 4/5
