What this MCCB carries and where it fits
The SENTRON 3VM1196-4EE46-0AA2 is a 4-pole molded case circuit breaker (MCCB) rated for 16 A continuous current across ambient temperatures from 40 °C to 55 °C, derating to 15 A at 60 °C through 70 °C. Its interrupting capacity hits 121 kA at 240 V AC, 76 kA at 415 V, 53 kA at 440 V, and 11.9 kA at 500 V — the S switching capacity class means it handles high fault currents typical of industrial distribution panels and motor control centers. The TM220 thermal-magnetic release provides LI protection (long-time and instantaneous), so it covers both overload and short-circuit faults without needing an external relay. Box terminals on the front simplify busbar or cable connections in a standard panel layout.
