The interrupting rating drops to 121 kA at 415 V, 30 kA at 440 V, and 17 kA at 690 V, so the voltage class of your distribution panel determines which fault-current number governs the SCCR calculation. The starter protection version means the release curve is shaped for motor-starting inrush — it rides through the momentary surge without nuisance tripping, then clears a locked-rotor fault. The continuous current is flat at 200 A from 40 °C through 50 °C, then derates to 192 A at 55 °C, 188 A at 60 °C, 184 A at 65 °C, and 180 A at 70 °C. The HQ designation means the trip alarm signals a separate contact that changes state only on a fault trip, not on manual switching — useful for remote fault annunciation in a PLC input. Dimensions are 158 mm height, 105 mm width, 70 mm depth. Front IP40 keeps tools and fingers out. The undervoltage release (UVR) is built in. The latching endurance is rated 15 000 operations, which is typical for an MCCB used in a motor branch circuit where the breaker is switched infrequently (the contactor handles daily cycling).","metaTitle":"Siemens 3VA1220-5MH32-0BH0 SENTRON MCCB, 200 A, 3-pole, star","metaDescription":"Siemens 3VA1220-5MH32-0BH0 SENTRON molded case circuit breaker, 200 A rated continuous, 3-pole, 187 kA at 240 V, TM120M release, undervoltage release, current lifecycle.
