The breaker is rated In = 25 A continuous current, with fixed overload protection at Ir = 25 A and fixed short-circuit protection at Ii = 12.8 × In (320 A). The 100% N conductor protection means the neutral pole is fully rated, not reduced — this matters for systems with harmonic loads or where the neutral carries near-phase current.","metaTitle":"Siemens 3VA1125-6GD42-0AA0-ZD00 Circuit Breaker, 70kA @ 415V","metaDescription":"Siemens 3VA1125-6GD42-0AA0-ZD00 IEC frame 160 circuit breaker, 70kA breaking capacity at 415V, 4-pole, 25A fixed thermal-magnetic.
