Integrator note — 3VA1010-4ED36-0CH0
The Siemens SENTRON 3VA1010-4ED36-0CH0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, with a continuous current Iu of 100 A and a TM210 thermal-magnetic release. Breaking capacity hits 121 kA at 240 V, 75.6 kA at 415 V, and 52.5 kA at 440 V — the 415 V figure is the one that matters for most European 400 V distribution panels. At 690 V it drops to 11.9 kA, so verify the fault level if this lands on a 690 V bus. Current rating holds flat at 100 A up to 50 °C ambient; above that it derates to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. If the panel runs hot — say a crowded enclosure near a furnace line — plan the load at the derated figure, not the nameplate 100 A. Front protection is IP40 — fine for a clean panel interior, not for washdown zones. Operating range spans -25 °C to 70 °C, storage from -40 °C to 80 °C. Built-in undervoltage release (UVR) is standard on this variant. Auxiliary contact block carries 2 auxiliary switches plus 1 trip alarm switch (HQ version). The integrated auxiliary trip order code is 3VA9608-0BB24.
