Rated current holds at 20 A from 40 °C up to 55 °C, then derates to 19 A at 60–70 °C — useful if the breaker sits near transformers or other heat sources inside the enclosure. Maximum power loss of 12 W means ventilation planning matters in a sealed cabinet. This breaker ships with a built-in shunt trip release (STL) and two auxiliary switches (HQ), so you can remote-trip and monitor status without adding external accessories.","metaTitle":"Siemens 3VA1020-2ED32-0HC0 SENTRON MCCB, 20 A, 3-Pole, 52.5","metaDescription":"Siemens SENTRON 3VA1020-2ED32-0HC0 molded case circuit breaker, 20 A, 3-pole, breaking capacity 52.5 kA at 240 V.

The 3VA1010-2ED32-0DC0 is a 3-pole, lower-current variant. Neither is a direct drop-in without verifying the interrupting rating and terminal spacing for your panel."},{"question":"What is the depth of 3VA1020-2ED32-0HC0?","answer":"The depth is 70 mm (2.76 in)."},{"question":"What is the width of 3VA1020-2ED32-0HC0?","answer":"The width is 76.2 mm (3 in)."},{"question":"Will 3VA1020-2ED32-0HC0 drop into a panel specified for 3VA1110-5EE32-0LC0 without rewiring?","answer":"Not without checking. The 3VA1110-5EE32-0LC0 is a higher-rated frame; terminal spacing and busbar cutouts may differ. Measure the mounting centers and compare the line/load lug positions against your existing buswork before assuming a swap."},{"question":"What compliance documentation does Siemens provide for 3VA1020-2ED32-0HC0?","answer":"Siemens SENTRON MCCBs typically carry UL, IEC, CSA, and CE certifications.
