SENTRON 3VM1096-3ED42-0AA0 — 4-pole MCCB, 16 A, TM210 trip
Breaking capacity is 76 kA at 240 V AC, 53 kA at 415 V AC, 32 kA at 440 V AC, and 7.5 kA at 500 V AC — the 415 V figure is the one most commonly checked for European 400 V distribution panels. The TM210 is a fixed thermal-magnetic trip with an adjustable response current (Ir) minimum of 16 A — meaning the thermal element is set at the factory and cannot be turned down below the frame rating.
Thermal derating and panel integration
Rated current holds at 16 A from 40 °C through 55 °C ambient; at 60 °C it derates to 15 A, at 65 °C to 14 A, and at 70 °C to 14 A. If the breaker sits in a warm enclosure — say, above a drive or transformer — use the 60 °C column for your wire sizing. Dimensions are 101.6 mm wide, 130 mm high, 70 mm deep — a 4-pole MCCB that fits a standard 100 mm DIN-rail pitch. Front IP40 means tools and fingers are protected; the back and sides are open to the panel interior. Rated insulation voltage (Ui) is 690 V AC, and maximum operational voltage for DC circuits is 500 V.
