That 36 kA interrupting rating at 415 V means it can safely clear a fault up to that level without upstream coordination issues in a 400/415 V distribution panel — the class S designation places it between standard and high-breaking variants in the 3VA1 family. The overload protection (Ir) is adjustable from 70 A to 100 A, and the short-circuit protection (Ii) is fixed at 5 to 10 times In — so at the 100 A setting, instantaneous trip is between 500 A and 1000 A. This makes it a fit for feeder circuits or downstream sub-distribution where you need a 100 A rated breaker with adjustable thermal pickup and a wide magnetic band. The suffix ZD00 indicates a special version that includes a nut keeper kit for DC Power OEM applications in China. That detail matters for BOM traceability: if your panel is built to a Chinese OEM spec requiring that hardware, the standard 3VA1110-4EF42-0AA0 will not match the kit content. ## Deployment context The 3VA1 frame 160 is a panel-mount MCCB designed for DIN-rail or screw-mount installation in low-voltage switchgear and distribution boards. The nut keeper kit included with this ZD00 variant simplifies assembly for OEMs building DC power distribution equipment — the kit keeps the mounting hardware captive during panel wiring.","metaTitle":"Siemens 3VA1110-4EF42-0AA0-ZD00 MCCB, 36kA @ 415V, 100A","metaDescription":"Siemens 3VA1110-4EF42-0AA0-ZD00 circuit breaker.
