That thermal stability matters when you're packing breakers tight in a panel where ambient heat builds. Breaking capacity is 75.6 kA at 240 V AC, 52.5 kA at 415 V, and 32 kA at 440 V — still 7.5 kA at 690 V. That's a high-interrupting rating for a 20 A frame, meaning it can clear serious fault current without the arc finding another path through the panel steel. That UVR is what drops the breaker if control voltage falls below the dropout threshold — common on safety circuits where a loss of control power needs to kill the load. The 70 mm depth means it won't crowd the gland plate on a 200 mm deep enclosure, but check your door clearance if the breaker has rotary handles or extended aux switches.","metaTitle":"Siemens 3VA1020-3ED32-0CC0 SENTRON MCCB, 3-Pole, 20 A, 75.6","metaDescription":"Siemens 3VA1020-3ED32-0CC0 SENTRON molded case circuit breaker. 3-pole, 20 A rated, 75.6 kA breaking at 240 V.
