The breaker carries a 40 A continuous rating (In) with a thermal-magnetic trip unit (TM220, ATFM). Overload protection (Ir) is adjustable from 28 A to 40 A, so you set the continuous current threshold to match the cable or load without swapping the breaker body. Short-circuit protection (Ii) is fixed at 10 times In — 400 A magnetic pickup — which suits motor circuits or feeders where a brief inrush should not cause nuisance tripping. The N conductor on this variant is unprotected, and the unit includes a nut keeper kit. The order code suffix -ZD00 indicates a configuration for a DC Power OEM in China, meaning the breaker ships with the accessory kit and a specific factory-set trip profile for that customer's BOM. For general distribution, the standard 3VA1 frame breaker without the -ZD00 suffix would be the typical choice; this variant is a direct-fit replacement for the OEM line it was built for.
