At 690 V the rating drops to 17 kA, and the same 17 kA applies at 500 V, so for 690 V applications verify the available fault current stays within that ceiling. The TM210 release has an adjustable short-circuit pickup up to 320 A (li max), giving flexibility to coordinate with downstream breakers or motor starters without changing the breaker frame. ## Thermal Performance and Derating The 3VA1120-6GD46-0AA0 carries its full 20 A rating from 45 °C through 55 °C ambient without derating — a solid margin for typical panel environments. Above 55 °C, the current rating steps down to 19 A at 60 °C, 65 °C, and 70 °C, so a panel running near its upper thermal limit loses only 1 A of headroom. Maximum power loss is 12 W at rated load — modest enough that forced ventilation is rarely needed in a standard enclosure. The breaker occupies a 101.6 mm wide, 130 mm tall, 70 mm deep footprint — standard for a 4-pole SENTRON 3VA frame — and mounts directly onto a DIN rail or panel-mount adapter. An optional motor drive accessory (Product Extension / Optional / Motor Drive: Yes) allows remote motorized operation for automated or inaccessible panels. ## Electrical Ratings and Compliance","metaTitle":"Siemens 3VA1120-6GD46-0AA0 SENTRON MCCB, 20A, 4-Pole, 220kA","metaDescription":"Siemens 3VA1120-6GD46-0AA0 SENTRON 4-pole MCCB, 20A rated, TM210 release, 220 kA at 240 V.
