At 415 V the rating drops to 32 kA; at 690 V it holds at 7.5 kA, reflecting the voltage-dependent arc extinction limits typical of MCCBs. Rated current holds at 20 A from 40 °C up to 55 °C, then derates to 19 A at 60–70 °C. That flat thermal curve means it can sit in a warm panel without losing headroom — useful for enclosures near motors or ovens. Maximum power loss is 12 W per pole — a useful figure for thermal management in a multi-breaker enclosure. ## Built-in accessories and panel integration The shunt trip allows remote tripping from a PLC or emergency-stop circuit; the auxiliary switches report breaker status back to the control system. Dimensions are 76.2 mm wide, 70 mm deep, 130 mm tall — a 3-pole footprint that fits standard Siemens SENTRON mounting and bus-bar systems.","metaTitle":"Siemens 3VA1020-2ED36-0HH0 SENTRON MCCB, 20 A, 3-Pole, 52.5","metaDescription":"Siemens 3VA1020-2ED36-0HH0 SENTRON molded case circuit breaker, 20 A at 40 °C, 3-pole, 52.5 kA at 240 V.

It shares the same 3-pole form factor and accessory architecture, so it can drop into the same panel footprint, but the current rating and breaking capacities differ — verify the load before substitution."},{"question":"What is 3VA1020-2ED36-0HH0's listed depth?","answer":"Listed depth is 70 mm (2.76 in)."},{"question":"What is 3VA1020-2ED36-0HH0's listed width?","answer":"Listed width is 76.2 mm (3 in)."},{"question":"Will 3VA1020-2ED36-0HH0 drop into a panel that was specified around 3VA1110-5ED36-0AC0 without rewiring?","answer":"Both breakers share the same SENTRON 3VA mounting footprint and bus-bar pitch, so the mechanical fit is the same. However, the 3VA1110-5ED36-0AC0 is a higher-current frame — verify the branch circuit conductor and upstream protection are sized for the 20 A rating before installing the 3VA1020-2ED36-0HH0."},{"question":"What compliance documentation does Siemens provide for 3VA1020-2ED36-0HH0?","answer":"Siemens SENTRON MCCBs carry UL, CSA, and IEC certifications as standard.
