Short-time pickup (Isd) is settable from 1.5× to 10× Ir, and the instantaneous pickup (Ii) is fixed at 10× In. The neutral conductor protection is also adjustable — OFF, 50%, or 100% of the phase current — which is useful for 4-wire systems where neutral loading varies. All of this is set on the trip unit face without needing external power or programming tools. This particular unit ships with a factory-installed 24 V DC undervoltage release accessory, intended for the 3VA1 and 3VA20 platform. The release is wired separately from the load circuit; verify polarity on the 24 V DC coil before energizing. ## Integration and mounting — DIN-rail or screw-mount panel fit At 160 A frame size, expect the breaker to occupy roughly four to six module widths — plan the enclosure fill factor accordingly, especially if you are retrofitting into an existing panel where busbar take-off points are fixed. The nut keeper kit mentioned in the description is a captive-nut accessory that simplifies screw-mounting in enclosures where the back-of-panel access is tight. The ETU350 is a self-powered electronic trip unit — it draws its operating energy from the current transformers around the phase conductors, so no auxiliary supply is needed for the protection functions. The undervoltage release, however, requires a separate 24 V DC supply; factor that into your control transformer sizing and fuse protection. Sourcing is handled on a quoted-to-order basis against an RFQ. Volume purchases or blanket-order agreements can be structured; lead time varies with factory backlog and should be requested at quote time.","metaTitle":"Siemens 3VA2116-5HN42-0BA0 Circuit Breaker, 160A, 55kA @ 415","metaDescription":"Siemens 3VA2116-5HN42-0BA0 IEC frame 160 MCCB, 55kA breaking capacity @ 415V, ETU350 LSI trip, 160A, 4-pole, with 24VDC undervoltage release.
