MODEL: MAT3 MAT3 SPECIFICATIONS ES-8164 Rev.3 Page 3/5 http://www.m-system.co.jp/ CONNECTION EXAMPLES EDEB 5)a 5)b N PE N PE N ■ INSTALLATION EXAMPLES: Three-phase 4-wire connection *1. The circuit breaker or the fuse as disconnectors must be installed. Molded-case circuit breaker (MCCB) or residual current circuit breaker with overcurrent protection (RCD) 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 MCCB (rated current 20 – 30A) that has element for each phase. Or RCD with protection from nuisance tripping against transit voltages type or time-delay overcurrent protection type is recommended. Recommended sensitivity current rating: 30mA *2. Cable length between the branch point and the earthing: 0.5 meters or less recommended *3. The protected device's metal enclosure must be cross-wired to the earth terminal of the MAT3. If the protected device has no earth terminal, earth only the MAT3. *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. 1) : Protective device of the switchgear 2) : Circuit breaker 3) : Main earth terminal or busbar 4) : MAT3 5) : Earth conductor 5)a and/or 5)b 6) : Protected device EB : Main's earth electrode ED : Switchgear's earth electrode Residual Current Circuit Breaker

For TT system, in order to ensure safe failure mode at TOV due to earth fault on high-voltage systems, connect between terminal 2 and N of the MAT3. *2. 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. *3. For single-phase/2-wire system, connect lines to terminal 1 and 2 of the MAT3. For single-phase/3-wire system, connect the neutral line to terminal 2 of the MAT3.
