Breaking capacity runs 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V. That spread covers most industrial distribution voltages in a single frame size — useful when the same breaker type appears across multiple panel voltage levels. The unit includes a trip indicator and voltage-trip flag for quick visual status on the panel face. ## Auxiliaries and Releases — Shunt Trip + Two Aux Switches Compared to a sibling like the 3VA1020-3ED36-0AA0, the 2ED32-0KH0 carries a lower continuous rating (20 A vs 36 A) and a different aux-switch complement. The physical footprint — 70 mm deep, 76.2 mm wide, 130 mm tall — is the same 3VA frame, so a panel laid out for one can accept the other without re-drilling the mounting holes or reworking the bus bars, provided the current and accessory fit match the BOM. ## Panel Integration — Footprint and Environment Dimensions are 130 mm high × 76.2 mm wide × 70 mm deep — a standard 3VA frame that mounts on DIN rail or directly to a backplate.","metaTitle":"Siemens 3VA1020-2ED32-0KH0 SENTRON MCCB, 20A 3-Pole, 52.5kA","metaDescription":"Siemens 3VA1020-2ED32-0KH0 SENTRON molded case circuit breaker, 20 A rated, 3-pole, line protection.
