What this MCCB delivers
The Siemens 3VA2010-5HM36-0AA0 is a 3-pole SENTRON molded case circuit breaker rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Breaking capacity hits 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. No undervoltage release, no communication module, no trip indicator — this is a straight line-protection breaker for dedicated feeder or branch circuits where remote signaling isn't required.
Three-pole footprint matches standard SENTRON 3VA2 busbar and lug kits; no special adapter needed for DIN-rail or screw-mount installation.
Ground-fault and environmental limits
Ground-fault monitoring uses summation current formation on the L-conductor — a residual-current detection method that sums phase currents to detect imbalance. Maximum power loss is 13.5 W, which matters for thermal budgeting in sealed enclosures.
