That thermal curve means this breaker doesn't force a panel de-rate until you're well above normal enclosure ambient. The TM220 overcurrent release combines a thermal element for overload and a magnetic element for short-circuit; the '220' designator indicates the magnetic pickup is fixed at 10× In (500 A), so it clears hard faults fast without nuisance tripping on motor inrush. Short-circuit breaking capacity is the headline number here: 187 kA at 240 V, 121 kA at 415 V, 76 kA at 440 V, and 17 kA at 500 V. At 500 V the 17 kA figure still covers most distribution panels. This MCCB mounts in a panel or enclosure — it's not a DIN-rail snap-on; it bolts to a mounting plate or busbar system.","metaTitle":"Siemens 3VM1150-5EE32-0AA0 SENTRON MCCB, 50 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VM1150-5EE32-0AA0 molded case circuit breaker, 50 A rated at 40 °C, 3-pole, TM220 release. 187 kA at 240 V.
