The Siemens SENTRON 3VA1216-4EF32-0BA0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current Iu of 160 A at 40 °C through 50 °C ambient — no derating needed in a standard 50 °C panel environment. At 55 °C it still holds 155.6 A, and at 70 °C it delivers 142.4 A, so the thermal curve is flat across most normal operating conditions.
Built-in undervoltage release — no add-on module needed
No auxiliary contact version is fitted, and there is no communication module or ground-fault monitoring on this build.
Dimensions: 105 mm wide, 158 mm high, 70 mm deep. Depth of 70 mm means it clears most standard gland-plate depths without protruding past the enclosure door.
