Breaking capacity is voltage-dependent: 76 kA at 240 V AC, 53 kA at 415 V, 32 kA at 440 V, and 8 kA at 500 V. For DC applications, the maximum rated operational voltage is 500 V DC, though the interrupting ratings for DC systems are covered in the separate 3VA MCCB manual. Thermal derating is minimal up to 55 °C — the breaker holds 20 A flat. At 60 °C it derates to 19 A, at 70 °C to 18 A. Maximum power loss is 12 W. No motor drive or communication function is fitted on this variant. The neutral conductor is not upgradeable or retrofittable.","metaTitle":"Siemens 3VM1020-3ED32-0AA0 SENTRON MCCB, 20 A, 3-Pole, 76 kA","metaDescription":"Siemens 3VM1020-3ED32-0AA0 SENTRON 3-pole molded case circuit breaker, 20 A rated at 40 °C, TM210 release, 76 kA at 240 V.
