SENTRON 3VA1125-5GD46-0AA0 — 25 A 4-Pole MCCB with TM210 Release
The TM210 thermal-magnetic release provides fixed overload and short-circuit protection curves — no interchangeable trip units, which simplifies specification for standard distribution panels. Breaking capacity is voltage-dependent: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V.
Thermal Derating and Operating Envelope
Above that, the breaker derates linearly: 24 A at 55 °C and 60 °C, then 23 A at 65 °C and 70 °C.
Dimensions are 101.6 mm wide (4 in), 130 mm tall (5.12 in), and 70 mm deep (2.76 in). The 4-pole width is the critical dimension for panel layout — standard Siemens SENTRON 3VA mounting accessories and busbar systems apply. No undervoltage release, no voltage trigger, and no communication function are fitted on this variant; the trip indicator is also absent, so fault indication relies on external annunciation or the breaker handle position.
