The interrupting capacity is the headline: 187 kA at 240 V, 121 kA at 415 V, 76 kA at 440 V, and still 17 kA at 500 V and 690 V. The 20 A continuous rating holds flat from 40 °C through 55 °C (no derating needed in a warm enclosure), then drops to 19 A at 60 °C and above. ## Panel integration and wiring notes The TM210 release is non-interchangeable; if the application needs a different trip curve or rating, you step to a different 3VA variant rather than swapping the trip unit in the field. ## Electrical ratings that govern the selection Maximum rated operational voltage with DC is 600 V, so this 4-pole breaker can also serve in DC combiner boxes or battery circuits if the poles are series-connected per the Siemens manual. No undervoltage release, no shunt trip, no ground-fault monitoring, and no communication module are fitted on this variant — it is a straight thermal-magnetic line-protection device with auxiliary contacts only.","metaTitle":"Siemens 3VA1010-4ED46-0AH0 SENTRON MCCB, 20 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA1010-4ED46-0AH0 molded case circuit breaker, 4-pole, 20 A rated, 187 kA interrupting at 240 V.
