What this MCCB carries
The Siemens 3VA2010-6HL32-0BL0 is a SENTRON molded case circuit breaker (MCCB) rated for 100 A continuous at 40 °C through 70 °C — no derating needed across that band. The adjustable thermal-magnetic trip unit covers 150 A to 1 200 A, so you set the actual protection point to match the downstream load, not the breaker frame. Three poles, line protection design, no communication module, no ground-fault monitoring built in. Interrupting capacity climbs with the voltage you're clearing: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V. That 242 kA figure at 240 V means it handles high-fault scenarios like transformer secondaries or large motor control centers without needing a current-limiting fuse upstream.
Auxiliary hardware onboard
This variant ships with a populated auxiliary switch block: 2 auxiliary switches + 1 trip alarm switch + 1 electrical alarm switch (HQ type). Also includes an undervoltage release (UVR). That means you get remote status and shunt-trip capability without buying add-on modules — just wire the UVR coil and the alarm contacts into your control circuit. The basic switch supplied is order code 3VA20106HL320AA0.
Panel fit and environment
Footprint is 105 mm wide × 181 mm tall × 86 mm deep — a standard 3-pole MCCB envelope that drops into most SENTRON panelboards and DIN-rail adapters. Operating range is -25 °C to 70 °C ambient; storage from -40 °C to 80 °C. Maximum power loss at rated current is 16 W, which matters for enclosure thermal rise calculations in sealed cabinets. Trip indicator is present, voltage trigger is not — the UVR handles undervoltage, but there's no separate voltage-trip coil. No ground-fault monitoring version on this order code, so if you need GF protection you step to a different suffix.
