Two auxiliary switches (HQ) plus a separate trip alarm switch (HQ) give status feedback for the controls integrator: one set for the breaker position, one for the faulted state. The N conductor is unprotected (solid neutral), so this is a 3-pole + N configuration, not a 4-pole protected neutral. Panel builders will note the nut keeper kit included for the busbar connection — no dropped hardware inside the enclosure.","metaTitle":"Siemens 3VA1050-3ED42-0HH0 circuit breaker, 50A, 25kA @ 415V","metaDescription":"Siemens 3VA1050-3ED42-0HH0 IEC frame 100 circuit breaker, 50A fixed overload, 25kA breaking capacity @ 415V, shunt trip, auxiliary switches.
