It carries a TM240 thermal-magnetic trip unit set at In=20 A, with overload protection adjustable from 14 A to 20 A and short-circuit protection at 8 to 16 times In. The neutral conductor is unprotected; a nut keeper kit is included for DC Power OEM applications in China. Rated for panel mounting in IEC switchgear assemblies, the 3VA1 frame fits standard DIN-rail or screw-fixed installations. The 70 kA Icu at 415 V provides high fault-current interruption without cascading upstream — suitable for main or branch feeder positions in industrial distribution boards.","metaTitle":"Siemens 3VA1120-6EF42-0AA0-ZD00 Circuit Breaker, 70kA @ 415V","metaDescription":"Siemens 3VA1120-6EF42-0AA0-ZD00 IEC frame 160 MCCB, 70kA breaking capacity @ 415V, 4-pole, TM240, In=20A, Ir=14-20A.
