The 3VA1196-5EF32-0KH0 is a SENTRON 3-pole molded case circuit breaker (MCCB) rated 16 A continuous at 40 °C, with a 121 kA interrupting capacity at 415 V AC.
Integrated accessories and panel fit
The auxiliary switches report breaker position (ON/OFF) and trip status back to a control system. No undervoltage release is fitted. Panel dimensions: 76.2 mm wide, 130 mm tall, 70 mm deep — three-pole width on a standard 25 mm/module grid.
Rated current holds at 16 A from 40 °C up to 55 °C, then derates to 15 A at 60 °C and stays at 15 A through 70 °C. That's a flat thermal curve — no derating step until 60 °C, which is better than many MCCBs that start dropping at 50 °C.
