SENTRON 3VA1196-5GD42-0AA0 — 16 A MCCB, 4-Pole, TM210 Release
Breaking capacity reaches 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V — figures that cover most industrial low-voltage fault-current scenarios without needing a current-limiting upstream device.
The 16 A rating holds flat from 40 °C through 55 °C ambient, then derates to 15 A at 60–70 °C. This means the breaker can be packed into a warm enclosure without losing capacity until the internal air temperature exceeds 55 °C — typical for a crowded panel with multiple devices dissipating heat. Rated insulation voltage is 800 V, and operating temperature spans -25 °C to +70 °C, with storage from -40 °C to +80 °C. Maximum power dissipation is 10.6 W. In a multi-breaker panel, that heat adds up; account for it in the enclosure thermal calculation to avoid cascading derating.
The 101.6 mm (4-inch) width is the standard SENTRON 3VA1 frame width for 4-pole units, so it fits existing cutouts and busbar layouts in Siemens panelboards and third-party enclosures designed for the 3VA family.
