The TM210 thermal-magnetic trip unit is set for a fixed 100 A overload (Ir) and a fixed 10x In short-circuit pickup (Ii), so it's a straight line-protection breaker, not a motor-protection or adjustable model. That's enough for most secondary distribution panels downstream of a 1 MVA transformer. The fixed Ir=100 A and Ii=10 x In (1000 A instantaneous) mean it's a set-and-forget device — no adjustment dials to mis-set during commissioning. The nut keeper kit is a small mechanical detail that matters on an assembly line: it prevents the mounting nuts from falling into the panel during installation, which is exactly the kind of thing that slows down a DC Power OEM build. The 'for DC Power OEM in China' tag in the order code means this variant was configured for that specific supply chain, but electrically it's a standard 3VA1 line-protection breaker.","metaTitle":"Siemens 3VA1110-4ED42-0AA0-ZD00 Circuit Breaker, 36 kA @ 415","metaDescription":"Siemens 3VA1110-4ED42-0AA0-ZD00 IEC frame 160 circuit breaker. 36 kA breaking capacity @ 415 V, 4-pole, TM210 trip, Ir=100 A, Ii=10 x In.
