The TM designation means the release is fixed, not electronic — no adjustable long-time or short-time pickup settings, so it's a straight swap for a panel that already expects that trip curve. Rated insulation voltage is 800 V, and the interrupting capacity runs 52.5 kA at 240 V, dropping to 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V — enough for most distribution and motor branch circuits in industrial panels. ## Temperature derating and panel fit","metaTitle":"Siemens 3VA1020-2ED36-0AC0 SENTRON MCCB, 20 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA1020-2ED36-0AC0 molded case circuit breaker, 20 A rated, 3-pole, TM210 release.
