At 690 V the breaker still clears 7.5 kA, which covers most industrial motor-drive circuits at that voltage level. Maximum power loss is 14.5 W — a figure to check against enclosure thermal rise in a densely packed panel. ## Built-in undervoltage release No ground-fault monitoring or communication module is fitted; this is a straight line-protection MCCB. The case measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard 3-pole MCCB footprint that drops into most SENTRON distribution panels without re-drilling the gland plate.","metaTitle":"Siemens 3VA1020-3ED36-0DC0 SENTRON MCCB, 3P, 20A, 75.6kA at","metaDescription":"Siemens SENTRON 3VA1020-3ED36-0DC0 molded case circuit breaker, 3-pole, 20 A rated, 75.6 kA breaking at 240 V.

The functional difference is the built-in undervoltage release on the -0DC0 variant versus the -0AA0 which lacks it. If the original panel wiring included the UVR coil connections, the swap is direct; if not, you need to add those two wires."},{"question":"What compliance documentation does this brand provide for 3VA1020-3ED36-0DC0?","answer":"Siemens SENTRON MCCBs carry UL, CSA, and CE certifications as standard.
