It is a line-protection device with a TM240 thermal-magnetic trip unit, rated In=25 A, with adjustable overload protection Ir from 18 A to 25 A and short-circuit protection Ii adjustable from 6.4 to 12.8 times In. The suffix ZD00 indicates a nut keeper kit included for DC Power OEM applications in China. ## What the adjustable trip settings mean for coordination The TM240 trip unit has a thermal adjustment band from 18 A to 25 A (Ir) and a magnetic adjustment from 6.4 to 12.8 x In (Ii). The nut keeper kit (ZD00 suffix) is factory-fitted for DC Power OEM builds — it retains the terminal nuts during wiring, a time-saver in high-volume panel assembly.","metaTitle":"Siemens 3VA1125-6EF32-0AA0-ZD00 Circuit Breaker, 70kA @ 415V","metaDescription":"Siemens 3VA1125-6EF32-0AA0-ZD00 IEC frame 160 circuit breaker, 70kA breaking capacity at 415V, 25A thermal-magnetic protection.
