It carries a 121 kA interrupting rating at 240 V, dropping to 75.6 kA at 415 V and 440 V, 52.5 kA at 500 V, and 3 kA at 690 V — the high fault-current headroom at the lower voltages makes it a fit for main or feeder duty in panels where available fault current is substantial.
N-conductor protection is adjustable OFF or 100%. Maximum power loss is 2.2 W — negligible for thermal budgeting inside a closed panel. Dimensions are 181 mm height, 140 mm width, 86 mm depth — the 140 mm width is the 4-pole form factor on this platform, so it occupies the same footprint as other 4-pole SENTRON 3VA breakers. Mounting is via screw terminals, not plug-in, so the panel builder wires directly to the lugs.
