Siemens SENTRON 3VA1010-2ED42-0JA0 — 100 A MCCB with Shunt Trip
The Siemens SENTRON 3VA1010-2ED42-0JA0 is a 4-pole molded case circuit breaker (MCCB) rated for line protection, carrying 100 A continuously at 40 °C ambient with no derating needed up to 50 °C. Its TM210 thermal-magnetic release provides fixed overload and short-circuit protection, while the integrated shunt trip (STL) allows remote tripping via a separate control voltage — useful for emergency-stop or interlock circuits where you need to drop the load without opening the main disconnect.
Rated breaking capacity reaches 52.5 kA at 240 V, 32 kA at 415 V, and 13.6 kA at 440 V — figures that cover most industrial distribution panels fed from a typical 400 V transformer. At 500 V and 690 V the rating holds at 7.5 kA, so this breaker can serve as a main or branch device in 480 V and 600 V class systems where the available fault current stays within that limit.
Current rating holds flat at 100 A from 40 °C through 50 °C, then derates to 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. Maximum power loss is 25 W at rated load — a figure to include in enclosure thermal calculations, especially in sealed or high-ambient panels.
Dimensions are 130 mm height, 101.6 mm width, and 70 mm depth — a standard 4-pole MCCB footprint that mounts on a DIN rail or panel-mount base. No trip indicator is fitted on this variant; the voltage-triggered shunt trip coil is the only auxiliary release.
