The 3VA2116-6HN42-0AF0: The 80–160 A adjustable thermal-magnetic (electronic) range means this breaker can be dialed down to protect a 90 A feeder or up to a 160 A main, without swapping the frame. The ETU350 trip unit provides LSIG (long-time, short-time, instantaneous, ground-fault) protection curves — ground-fault monitoring is not fitted on this variant (the listing shows 'without'), so if you need GF protection you'd step to a -0A... suffix with the G function. At 690 V the 3.7 kA figure is a hard limit — do not assume the same fault-clearing capability at higher line voltages.
Integration and panel fit
Dimensions: 181 mm height, 140 mm width, 86 mm depth. The 140 mm width is the standard 4-pole MCCB footprint — it occupies four 35 mm DIN-rail modules (roughly 140 mm total).
