The TM120M overcurrent release gives thermal-magnetic trip characteristics: thermal for overloads, magnetic for short circuits. ## Breaking capacity — where it clears faults This MCCB delivers 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. That's a high-interrupting rating for a 160 A frame — it'll clear severe fault currents without rupturing, which matters when you're coordinating downstream devices in a distribution panel. ## Thermal derating and ambient limits Rated current holds at 160 A from 40 °C through 50 °C (–), then steps down: 156 A at 55 °C, 151 A at 60 °C, 147 A at 65 °C, and 142 A at 70 °C. ## Undervoltage release and auxiliary wiring There's no trip indicator and no communication function, so this is a straightforward hardwired breaker, not a smart breaker with remote monitoring. Dimensions: 105 mm wide, 158 mm tall, 70 mm deep. The 35.5 W maximum power loss means it dissipates heat into the enclosure; factor that into your thermal budget if you're packing multiple breakers in a small cabinet.","metaTitle":"Siemens 3VA1216-5MH32-0DA0 SENTRON MCCB, 160A, 3-Pole, 187kA","metaDescription":"Siemens SENTRON 3VA1216-5MH32-0DA0 molded case circuit breaker, 160A rated at 40°C, 3-pole, 187kA breaking at 240V.
