It carries the ETU850 electronic trip unit, configurable for line protection. Interrupting capacity hits 330 kA at 240 V, 242 kA at 415 V, and 7.5 kA at 690 V — numbers that govern selectivity coordination in high-fault panels.
Lifecycle status is current — no end-of-life notice, no last-time-buy trigger.
Compared to the 3VA1112-5EF32-0CA0 (a 3-pole, 125 A frame), this 4-pole 250 A unit with the ETU850 trip offers higher continuous rating and full-rated neutral protection. The 5SQ2670-2YA16 and 5SQ2670-0KA15 are older-generation Siemens MCCBs; the 3VA series uses a different mounting footprint and trip-unit interface, so a panel built for those will likely need rework to accept this breaker.
Dimensions: 184 mm wide, 248 mm tall, 110 mm deep. Rated insulation voltage 800 V. The ETU850 trip unit includes communication and other measurement functions, which means it can feed data to a higher-level monitoring system over the breaker's internal bus.
