It carries a TM210 thermal-magnetic trip block set for fixed overload protection at Ir=40 A and fixed short-circuit protection at Ii=10 x In, with the N conductor left unprotected. The ZD00 suffix signals a variant configured with a nut keeper kit for DC Power OEM applications in China. In a distribution panel, that SCCR headroom allows it to be installed upstream of downstream breakers with lower interrupting ratings, provided the selectivity tables in the Siemens selectivity manual are followed. For a 40 A feeder on a 400 V line, the margin between the fault rating and the load current is wide enough that coordination with a downstream 25 A or 32 A MCB is straightforward.","metaTitle":"3VA1140-5ED42-0AA0-ZD00 circuit breaker, 55kA @ 415V, 40A","metaDescription":"3VA1140-5ED42-0AA0-ZD00 circuit breaker by Siemens. 3VA1 IEC frame 160, 55kA Icu @ 415V, 4-pole, 40A fixed overload, 10xIn short-circuit.
