SENTRON 3VA1025-3ED32-0AD0 — 25 A MCCB, TM210 Release
Thermal derating is modest: it holds 25 A from 40 °C to 50 °C, drops to 24 A at 55–60 °C, and 23 A at 65–70 °C — so in a warm panel you lose roughly 8 % of the continuous rating. Interrupting capacity is voltage-dependent: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V — high enough for most industrial distribution boards, but at 690 V you are limited to 7.5 kA fault current.
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that clips onto DIN rail or mounts via the rear screw terminals.
