What this MCCB is and where it fits
The Siemens 3VA2010-5HL36-0AH0 is a SENTRON 3VA2 molded case circuit breaker (MCCB) rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. It is a 3-pole line-protection device, meaning it sits at the feeder or main distribution point in a panel, not on a motor branch. The 187 kA breaking capacity at 240 V and 121 kA at 415 V give it the headroom to handle high-fault utility feeds without cascading upstream. Panel integration is straightforward: the 105 mm width fits standard MCCB mounting footprints, and the 86 mm depth leaves room for wiring gutters.
Breaking capacity — what the numbers mean for coordination
The 3VA2010-5HL36-0AH0 delivers 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. That steep drop at 690 V is typical for a 100 A frame — the arc energy at that voltage limits the interruption capability. For a 480 V panel (common in North America), the 121 kA at 440 V is the closest reference; it means this breaker can sit behind a transformer with a high available fault current without needing a current-limiting fuse upstream. The 3 kA at 690 V is enough for most 690 V motor control centers, but not for high-fault 690 V utility ties.
Auxiliary switch configuration and trip indication
The breaker ships with 2 auxiliary switches plus 1 trip alarm switch (HQ type) built into the supplied basic switch (order code 3VA20105HL360AA0). A trip indicator is present on the front face — useful for remote status monitoring via the alarm contact. No undervoltage release, no ground-fault monitoring, and no communication function are included on this variant.
Environmental limits and power loss
Operating temperature range is -25 °C to 70 °C; storage range extends from -40 °C to 80 °C. Maximum power loss is 13.5 W at rated current — a modest figure that keeps enclosure heat rise manageable in a standard panel. Rated insulation voltage is 800 V.
