The interrupting capacity is what you need to check against your available fault current: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 4.5 kA at 690 V. ## Integration — Panel Fit and Thermal Management The trip indicator is present, so you get a visual flag on a fault without needing to meter the load side. The design is explicitly for starter protection — meaning it's coordinated for motor-starting inrush and overload profiles, not just distribution feeder duty.","metaTitle":"Siemens 3VA1220-5MH32-0AF0 SENTRON MCCB, 200 A, 3-Pole, TM12","metaDescription":"Siemens 3VA1220-5MH32-0AF0 SENTRON molded case circuit breaker, 200 A rated, 3-pole, TM120M thermal-magnetic release, 70 mm depth.
