The 50 A continuous rating holds flat from 40 °C to 50 °C, then derates to 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. The TM210 release is a thermal-magnetic type — thermal element handles overloads (inverse time), magnetic element handles short-circuits (instantaneous). It's a straight line-protection breaker: feed it, protect the cable, trip on fault. No auxiliary signaling. ## Interrupting capacity by voltage Interrupting capacity drops as voltage rises: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. At 690 V the breaker still clears 11.9 kA — enough for most 690 V distribution, but verify against your transformer's fault current. Dimensions: 76.2 mm wide (3 in), 130 mm tall (5.12 in), 70 mm deep (2.76 in).","metaTitle":"Siemens 3VA1150-4ED32-0AA0 SENTRON MCCB, 50 A, 3-Pole, 121 k","metaDescription":"Siemens 3VA1150-4ED32-0AA0 SENTRON 3-pole MCCB, 50 A continuous, TM210 release, 121 kA at 240 V.
