What this MCCB delivers in the panel
The Siemens 3VA1010-3ED42-0AA0 is a 4-pole molded case circuit breaker from the SENTRON series, rated 100 A continuous at 40 °C and carrying a TM210 thermal-magnetic release. That TM210 designation means the thermal element is fixed at 100 A and the magnetic pickup is fixed at 10× In — no field-adjustable trip settings, so it's a straight swap-in for a feeder or distribution circuit where coordination is already set. The 75.6 kA interrupting rating at 240 V gives headroom for high-fault utility feeds; at 415 V it still breaks 52.5 kA, and at 690 V it holds 7.5 kA. That's a class-leading short-circuit rating for a 100 A frame, useful when the available fault current at the panelboard is known to be high.
Thermal derating and panel integration
The 100 A rating holds flat from 40 °C to 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. If the enclosure ambient runs hot — say a crowded panel near a furnace line — you lose about 9 % of capacity at the top end. The footprint is 70 mm deep by 101.6 mm wide by 130 mm tall, which is the standard 4-pole SENTRON 3VA1 frame. It snaps onto DIN rail; the IP40 front face keeps dust out of the enclosure cutout. Power loss is 25 W maximum, so factor that into the panel thermal budget if you're stacking several breakers in a sealed cabinet.
What's on the nameplate and what isn't
Rated insulation voltage is 800 V. The breaker has no undervoltage release, no shunt trip (voltage trigger), no communication module, no ground-fault monitoring, and no N-conductor protection — it's a straight thermal-magnetic line-protection device. The trip indicator is absent, so you won't get a visual flag on the front when it trips; you'll need to check the handle position or add an auxiliary contact if remote status is required. Storage range is -40 °C to 80 °C; operating range is -25 °C to 70 °C.
