The Siemens SENTRON 3VA1010-2ED42-0KH0 is a 4-pole molded case circuit breaker (MCCB) rated for 100 A at 40 °C ambient, with a breaking capacity of 52.5 kA at 240 V AC. The 100 A frame at 40 °C holds flat 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 — useful if the breaker sits in a warm enclosure or near other heat sources. Breaking capacity steps down with voltage: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V.
Auxiliaries and releases — what's built in
The HQ block gives status feedback: one set for breaker position (open/closed), one for trip indication. There's no undervoltage release on this order code, and no ground-fault monitoring module. If you need UVR or GF protection, you'd step to a different suffix. The trip indicator flag is present, so a quick visual check at the panel door confirms a trip event. Power loss is listed at 25 W maximum — that's the heat the breaker dissipates at full rated current.
Dimensions: 130 mm height, 101.6 mm width, 70 mm depth. The 101.6 mm width (4 inches) is standard for a 4-pole MCCB in this frame size — it'll fit existing SENTRON 3VA panel footprints and most DIN-rail or backplate mounting patterns. Depth of 70 mm is shallow enough for compact enclosures.
