It is configured for line protection with a TM220 thermal-magnetic trip unit, ATFM (adjustable thermal, fixed magnetic) settings: overload protection Ir adjustable 18 A to 25 A, and short-circuit protection Ii fixed at 12.8 × In (320 A at the 25 A setting). The unit includes a nut keeper kit and is designated for DC Power OEM applications in China. The 25 A continuous rating with adjustable overload (18–25 A) gives the specifying engineer flexibility to match the exact load current without changing the breaker frame. The fixed magnetic trip at 12.8 × In (320 A) provides instantaneous short-circuit protection; this multiplier is typical for motor-circuit or general-purpose line protection where high inrush must be tolerated without nuisance tripping. ## Integration Notes The nut keeper kit (included per the order code suffix) secures the breaker against vibration in OEM builds — relevant for DC Power OEM installations in China where the part is destined. The 3-pole configuration covers three-phase line protection; verify the neutral conductor protection requirement separately if a 4-pole unit is needed.","metaTitle":"Siemens 3VA1125-4EE32-0AA0-ZD00 Circuit Breaker, 25A, 36kA @","metaDescription":"Siemens 3VA1125-4EE32-0AA0-ZD00 IEC frame 160 circuit breaker, 3-pole, 25A, Icu=36kA @ 415V.
