Breaking capacity reaches 187 kA at 240 V AC, tapering to 121 kA at 415 V, 76 kA at 440 V, and 30 kA at 500 V — sufficient for high-fault utility feeds or transformer secondaries where upstream SCCR demands a robust interrupt rating. The 160 A rating holds flat from 40 °C through 50 °C, then derates to 155.6 A at 55 °C, 151.2 A at 60 °C, 146.8 A at 65 °C, and 142.4 A at 70 °C. Maximum power loss is 33 W at full load. The TM120M release is a thermal-magnetic type — no electronic adjustment, no ground-fault or communication functions. That keeps it simple and reliable for fixed-load feeders, but limits selectivity tuning compared to an electronic-trip MCCB. For DC applications, the manufacturer directs you to the 3VA Molded Case Circuit Breaker Manual for switching capacity values; this listing does not carry DC ratings directly.","metaTitle":"Siemens 3VM1216-5MH32-0AA0 SENTRON MCCB 160A, 187kA at 240V","metaDescription":"Siemens SENTRON 3VM1216-5MH32-0AA0 molded case circuit breaker, 3-pole, 160A, 187kA at 240V AC.
