For a panel builder coordinating downstream feeders, that 36 kA figure sets the upstream SCCR floor; anything fed from this breaker must have a lower withstand rating. The thermal overload is adjustable from 22 A to 32 A (Ir), and the magnetic short-circuit pickup is fixed at 5 to 10 times In — so at the 32 A setting, instantaneous trip occurs between 160 A and 320 A. The neutral conductor is unprotected (N conductor unprotected), meaning the breaker switches but does not protect the neutral leg; this is standard for IEC distribution where the neutral is bonded at the source. The 3VA1 frame is a standard panel-mount MCCB — it bolts into a distribution board or motor control center via the rear terminals, and the nut keeper kit (included per the order-code suffix) simplifies captive-fastener installation for OEM builds. The 4-pole configuration handles three-phase plus switched neutral (unprotected), common in IEC 61439-2 power-distribution assemblies. The 36 kA Icu at 415 V gives adequate fault-clearing headroom for most industrial service-entrance and sub-distribution applications.","metaTitle":"Siemens 3VA1132-4EF42-0AA0-ZD00 Circuit Breaker, 36kA @ 415V","metaDescription":"Siemens 3VA1132-4EF42-0AA0-ZD00 IEC frame 160, 4-pole, 36kA breaking capacity at 415V, TM240, In=32A.
