160 A MCCB with ETU860 — selectivity and communication in a 4-pole frame
The interrupting ratings are the headline: 187 kA at 240 V AC, 121 kA at 415 V and 440 V AC, 75.6 kA at 500 V AC, and 3.7 kA at 690 V AC — figures that cover most industrial service-entrance and feeder applications.
The drop to 75.6 kA at 500 V and 3.7 kA at 690 V is typical for this frame size; at 690 V you are near the upper voltage limit, so verify the available fault current at that voltage against the 3.7 kA ceiling.
Integration notes
The 3VA2116-5KQ46-0AA0 mounts in a standard panel or enclosure footprint. Dimensions are 181 mm height, 140 mm width, and 86 mm depth. The ETU860 trip unit is adjustable, and the N-conductor protection can be set to OFF or between 20 % and 100 % of the phase current. The communication function allows remote monitoring and control via the SENTRON bus system. Maximum power loss is 25.5 W.
