It carries a breaking capacity Icu of 25 kA at 415 V (class N), with an overload protection setting Ir adjustable from 18 A to 25 A and a fixed short-circuit protection Ii of 12.8 × In. The N conductor is unprotected, and the breaker includes a nut keeper kit — a detail that matters when you're torquing down lugs in a tight panel and don't want to lose a fastener into the cabinet floor. The TM220 thermal-magnetic trip gives you a fixed magnetic pickup at 12.8 × In (320 A at the 25 A In setting), which means it will hold through motor inrush without nuisance tripping while still clearing a hard short. The adjustable Ir band (18-25 A) lets you fine-tune the overload protection to match the continuous load current, so you don't have to swap the breaker if the load draws 22 A instead of 25 A. The nut keeper kit is a small but practical inclusion — it prevents the terminal nut from falling out during wiring, saving a few seconds per connection on a build of multiple breakers.","metaTitle":"Siemens 3VA1125-3EE42-0AA0-ZD00 Circuit Breaker, 25A, 25kA @","metaDescription":"Siemens 3VA1125-3EE42-0AA0-ZD00 IEC frame 160 circuit breaker, 25A, Icu=25kA @ 415V, 4-pole, TM220, ATFM.
