Siemens SENTRON 3VA2010-8HL36-0AA0 — 100 A MCCB with ETU320
The Siemens SENTRON 3VA2010-8HL36-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous at 40 °C through 70 °C — no derating needed across that band. That makes it a straight drop-in for a 100 A feeder or main breaker in a panel that runs warm; you don't lose headroom as the cabinet heats up. Breaking capacity hits 440 kA at 240 V AC, 330 kA at 415/440 V, 220 kA at 500 V, and 52.5 kA at 690 V. For a 100 A frame, those numbers mean it handles high-fault scenarios downstream of a large transformer without needing a current-limiting fuse upstream — the MCCB itself clears the fault. The ETU320 electronic trip unit gives adjustable overload and short-circuit protection curves. No voltage trigger, no ground-fault monitoring, no communication module on this variant — it's a line-protection breaker, not a motor-protection or smart breaker. The IP40 front protection suits enclosed panel mounting.
Footprint and panel fit
At 105 mm wide, 181 mm tall, and 86 mm deep, this breaker fits the standard SENTRON 3VA frame footprint. It mounts on DIN rail or can be screw-fixed to a backplate. The 86 mm depth is the body only — allow clearance for outgoing cable bends and the optional motor drive (the product extension is available).
