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 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. 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
A trip indicator is present on the front face — useful for remote status monitoring via the alarm contact.
Environmental limits and power loss
Maximum power loss is 13.5 W at rated current — a modest figure that keeps enclosure heat rise manageable in a standard panel.
