Above that, it derates linearly: 19.2 A at 55 °C, 18.8 A at 60 °C, 18.4 A at 65 °C, and 18 A at 70 °C. The TM210 release is fixed thermal, not adjustable, so that derating curve is the only headroom you get. The breaker occupies 76.2 mm width, 130 mm height, and 70 mm depth — a standard 3-pole MCCB footprint for the SENTRON 3VA platform. No trip indicator on this variant, so plan for an external indication circuit if the panel requires local fault annunciation.","metaTitle":"Siemens 3VA1020-3ED32-0AD0 SENTRON MCCB, 20 A, 3-pole, 75.6","metaDescription":"Siemens SENTRON 3VA1020-3ED32-0AD0 molded case circuit breaker, 20 A rated, 3-pole, interrupting 75.6 kA at 240 V.
