The electronic trip unit is an ETU350, giving you adjustable long-time, short-time, and instantaneous protection curves without swapping trip packs. This is a current-production part, not a phase-out line. At 240 V the 440 kA rating is effectively unlimited for most downstream gear — you can coordinate this breaker with branch MCCBs or MCBs without worrying about cascading failure. At 415 V the 330 kA still covers the highest fault levels found in industrial switchboards. The ETU350's adjustable I²t on short-time delay lets you set intentional delay for full selectivity with downstream breakers, which is the main reason you spec an electronic trip over a thermal-magnetic on a main or feeder. That 86 mm depth is the key dimension for enclosure selection — it fits standard 200 mm deep distribution boards with room for rear cabling. The 4-pole format with adjustable N-conductor protection (OFF or 100%) lets you configure it for 3-phase + neutral or 3-phase without neutral monitoring.","metaTitle":"Siemens 3VA2163-8HN46-0AA0 SENTRON 4P MCCB, 63 A, ETU350, 44","metaDescription":"Siemens SENTRON 3VA2163-8HN46-0AA0 molded case circuit breaker, 4-pole, 63 A, ETU350 electronic trip unit, 440 kA at 240 V.

The depth is the same at 86 mm. The difference is the trip unit — the 8HN46 carries an ETU350 electronic trip, while the 8HM32 uses a thermal-magnetic trip.
