Interrupting capacity runs 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, 17 kA at 500 V, and 11.9 kA at 690 V — so it handles high-fault utility feeds downstream of a transformer. The shunt trip coil draws power from a separate control circuit; verify the voltage rating of the STL against your control transformer before wiring. Power loss maxes out at 33 W at rated load — account for that heat in the enclosure thermal calculation if you're stacking breakers tight.","metaTitle":"Siemens 3VA1216-4EF32-0KA0 SENTRON MCCB, 160A, 3-Pole, TM240","metaDescription":"Siemens SENTRON 3VA1216-4EF32-0KA0 molded case circuit breaker, 160A at 40°C, 3-pole, TM240 release, shunt trip (STL), 121kA at 240V.

For a 480 V system, the value falls between those two points — expect roughly 35 kA, but selectivity studies should use the 500 V figure for conservative coordination."},{"question":"What does the TM240 release mean?","answer":"TM240 is the thermal-magnetic trip unit designation. The thermal pickup is set to 160 A continuous (the frame rating), and the magnetic short-circuit pickup is fixed at 240 A — meaning it will hold motor inrush without nuisance tripping but still clear a hard fault quickly."},{"question":"Where can I buy 3VA1216-4EF32-0KA0 and how is it quoted?","answer":"This part is sourced through independent distribution and quoted to order against an RFQ.
