The TM120M thermal-magnetic release handles overloads and short-circuits without a separate trip unit. Breaking capacity hits 121 kA at 415 V, dropping to 75.6 kA at 440 V and 30 kA at 500 V — enough for most industrial secondary-distribution panels, but check your point-of-fault current. The built-in shunt trip (STL) allows remote emergency-off or undervoltage tripping, though there's no ground-fault monitoring version on this variant. ## Sizing and derating — the real limits This breaker is designed for starter protection (motor branch-circuit), not feeder duty. The 160 A rating is at 40 °C; at 55 °C it's still 156 A, at 70 °C it's 142 A. Power loss maxes at 33 W, which matters for thermal coordination in a sealed cabinet. The shunt trip (STL) auxiliary release needs a separate control signal — typically 24 VDC or 230 VAC, depending on the coil ordered — wired to the breaker's auxiliary terminals. Insulation voltage rated 800 V, so it's fine for 690 V line-to-line systems (though the breaking capacity at 690 V drops to 4.5 kA).","metaTitle":"Siemens SENTRON 3VA1216-5MH32-0KA0 MCCB, 160 A, 3-Pole, 121","metaDescription":"Siemens SENTRON 3VA1216-5MH32-0KA0 molded case circuit breaker, 160 A continuous, 3-pole, 121 kA SCCR at 415 V.

At 440 V it's 75.6 kA, at 500 V it's 30 kA, and at 690 V it's 4.5 kA. Use the point-of-fault current to verify the rating for your installation."},{"question":"What does the TM120M release mean?","answer":"TM120M is a thermal-magnetic overcurrent release. The thermal element provides inverse-time overload protection; the magnetic element provides instantaneous short-circuit protection. The '120' indicates the frame size, and 'M' denotes the magnetic trip setting range. No separate trip unit is needed."},{"question":"Does this breaker include a shunt trip?","answer":"Yes, it includes a shunt trip (STL) auxiliary release for remote tripping. There is no undervoltage release on this variant.
