What this MCCB is and what it carries
The Siemens SENTRON 3VA2010-5HN36-0JL0 is a 3-pole 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. It is designed for line protection in distribution panels, meaning its trip curve and interrupting ratings are tuned for feeder and branch-circuit fault clearing, not motor or generator protection.
Breaking capacity — the number that decides selectivity
This breaker 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. Those are the maximum prospective fault currents it can safely interrupt at each voltage level. For a panel engineer coordinating downstream devices, the 121 kA at 415 V is the figure that governs whether this breaker holds selectivity with upstream gear or needs a current-limiting upstream device.
Auxiliary and release configuration
Factory-fitted with 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch (HQ configuration), plus a shunt trip release (STL). That means remote tripping and status feedback are built in — no separate add-on modules needed for basic remote signaling. The shunt trip allows a PLC or safety relay to force the breaker open on command, which is standard for emergency-stop circuits or remote load shedding.
Physical fit and panel integration
Mounts on a standard DIN rail or directly to a backplate. Dimensions: 105 mm wide, 181 mm tall, 86 mm deep. The 105 mm width is a standard 3-pole MCCB footprint — it occupies the same slot as other SENTRON 3VA2 frame breakers, so swapping between variants in the same panel layout requires no drilling or busbar rework.
