Overload protection is adjustable Ir=35…50 A; short-circuit pickup is fixed at Ii=10 x In (500 A). The N conductor is unprotected (solid neutral), meaning this breaker switches and protects the three phases only — the neutral passes through unswitched. The nut keeper kit is a mechanical accessory for DC Power OEM builds in China, not a functional rating. ## Deployment context The 4-pole form factor with unprotected neutral is typical for three-phase distribution where the neutral is bonded to ground at the service entrance and does not require overcurrent protection — common in IEC switchgear for commercial and light industrial panels.","metaTitle":"Siemens 3VA1150-5EE42-0AA0-ZD00 circuit breaker, 50 A, 55 kA","metaDescription":"Siemens 3VA1150-5EE42-0AA0-ZD00 IEC frame 160 MCCB, 4-pole, 50 A, Icu=55 kA @ 415 V.
