The TM210 thermal-magnetic trip unit provides fixed thermal and magnetic pickup; no adjustments, no voltage-trip or communication modules on this variant. Rated 25 A from 40 °C through 50 °C, then steps down to 24 A at 55 °C and 60 °C, and 23 A at 65 °C and 70 °C. For a 40 °C panel ambient the full 25 A is available; above that, apply the derating curve. The 70 mm depth and 101.6 mm width fit standard 4-pole MCCB panel cutouts — check the mounting footprint against the existing backpanel layout if retrofitting. Interrupting ratings: 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, 11.9 kA at 500 V and at 690 V. Current-production status per the manufacturer.","metaTitle":"SENTRON 3VA1025-4ED42-0AA0 MCCB, 25 A, 4-Pole, TM210, 121 kA","metaDescription":"SENTRON 3VA1025-4ED42-0AA0 molded case circuit breaker, 25 A rated, 4-pole, TM210 trip unit, 121 kA breaking capacity at 240 V AC.
