The TM210 thermal-magnetic trip unit handles the overload curve and short-circuit response — fixed thermal, fixed magnetic, no adjustment dials, which keeps the part simple and the BOM repeatable. This MCCB interrupts 52.5 kA at 240 V AC, 32 kA at 415 V, and still clears 7.5 kA at 690 V — so it handles high available fault current on the secondary side of a 480 V transformer without needing a current-limiting fuse upstream. The 800 V rated insulation voltage (Ui) means it's rated for 690 V systems with margin; you can land it in a 480/277 V or 600 V panel without worrying about creepage clearance. Three-pole, 70 mm deep, 76.2 mm wide, 130 mm tall — it fits standard 3-pole MCCB mounting footprints in a distribution panel or motor control center; the IP40 front face keeps fingers out but expects a sealed enclosure for washdown areas.","metaTitle":"Siemens 3VA1020-2ED36-0AA0 SENTRON MCCB, 20A, 52.5kA at 240V","metaDescription":"Siemens SENTRON 3VA1020-2ED36-0AA0 molded case circuit breaker, 3-pole, 20A rated, TM210 trip unit, 52.5kA breaking capacity at 240V.
