The Siemens SENTRON 3VA2010-5HN36-0JC0 is a 3-pole molded case circuit breaker rated for 100 A continuous current across the full operating temperature range from -25 °C to 70 °C — no derating needed up to 70 °C, which is a solid feature for a warm panel. It carries a massive 187 kA interrupting capacity at 240 V, dropping to 121 kA at 415/440 V, 75.6 kA at 500 V, and 3 kA at 690 V. That kind of short-circuit rating means it can sit upstream of a high-fault transformer or a big motor control center and still clear a dead short without welding its contacts shut.
What the ratings mean for your panel
A 100 A frame with 187 kA SCCR at 240 V is unusual — most 100 A MCCBs top out around 65-100 kA. This one is sized for high-fault locations like the service entrance of a large industrial plant or a substation feeder. The 3-pole design handles three-phase loads up to 100 A continuous. The shunt trip (STL) auxiliary release lets you remotely trip the breaker from a safety circuit or emergency-stop chain — no undervoltage release on this variant, so the shunt trip is the only remote-trip option. Two HQ auxiliary switches give you status feedback for the PLC or annunciator panel.
Panel integration
Mounts on DIN rail or direct panel-mount using the standard 3VA footprint. The 86 mm depth leaves room for wiring behind the breaker in a shallow enclosure. The shunt trip and auxiliary switches are factory-installed — no field-assembly required. No communication module on this variant, so it's a standalone thermal-magnetic breaker; trip indication is via the auxiliary switches, not a local flag.
