The interrupting ratings step down with voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V. At 415 V the 52.5 kA figure gives selectivity headroom against a 50 kA prospective fault — useful when coordinating downstream MCBs in a multi-level panel. ## Thermal derating and ambient limits Full 20 A rating holds through 50 °C ambient. In a sealed panel with multiple breakers ganged, factor the 55 °C+ derating into the load schedule. ## Auxiliaries and trip options The 3VA platform is Siemens' active MCCB family, so factory support and replacement auxiliaries are standard.","metaTitle":"Siemens 3VA1020-3ED32-0KH0 SENTRON MCCB, 20 A, 3-Pole, TM210","metaDescription":"Siemens SENTRON 3VA1020-3ED32-0KH0 molded case circuit breaker, 20 A rated, 3-pole, TM210 thermal-magnetic release, 75.6 kA at 240 V.

Both are 3-pole 20 A SENTRON MCCBs on the same frame, so they share the same mounting footprint and bus-bar spacing. The deciding factor is the auxiliary and trip block fit — verify the existing panel's auxiliary wiring matches the 2-switch + 1-alarm layout of this -0KH0 variant before swapping."},{"question":"What compliance documentation does this brand provide for 3VA1020-3ED32-0KH0?","answer":"Siemens SENTRON MCCBs carry CE marking, UL/CSA listings per the 3VA series, and RoHS/REACH declarations.
