The neutral pole is switched only, with no overload or short-circuit protection. Because this is a configured OEM variant (ZD00 suffix), availability may be less predictable than a standard catalog breaker. Mounts in the standard 3VA1 DIN-rail or screw-mount footprint — 4-pole frame takes the same panel cutout as the 3-pole plus one neutral pole width. The nut keeper kit is pre-installed on the DC-power terminals; verify torque spec on the nameplate before landing lugs.","metaTitle":"Siemens 3VA1125-3ED42-0AA0-ZD00 Circuit Breaker, 25A, 25kA @","metaDescription":"Siemens 3VA1125-3ED42-0AA0-ZD00 IEC frame 160 circuit breaker, 25A TM210, 25kA Icu @ 415V, 4-pole.
