What this 160 A MCCB delivers
Three poles, ETU860 electronic trip unit with communication function built in. The interrupting ratings are the headline: 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 53 kA at 690 V. That puts it in the high-breaking-capacity class for industrial main feeders and large sub-distribution where fault currents are severe.
Power loss is 19.7 W maximum, manageable for thermal coordination inside the enclosure. The ETU860 electronic trip unit gives you adjustable response times: tr from 0.5 to 20 seconds, tsd up to 0.5 s. That allows selectivity coordination with downstream breakers — you can delay the trip long enough for a branch breaker to clear a fault without taking the main feeder offline. The communication function means it can report status and trip events to a BMS or PLC, useful for remote monitoring in larger facilities.
Dimensions are 181 mm height, 105 mm width, 86 mm depth. That's a 3-pole frame that fits standard SENTRON mounting patterns in distribution panels.
