The Siemens SENTRON 3VA2010-5HN36-0KA0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full -25 °C to 70 °C operating range — no derating needed as the panel warms up. It's designed for line protection and comes with an integrated shunt trip (STL) release for remote tripping, common in emergency-stop or supervisory control circuits.
Breaking capacity and selectivity
Breaking capacity is 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3 kA at 690 V. That 187 kA at 240 V gives serious fault-current headroom on low-voltage distribution — useful for high-fault panels where a standard 65 kA MCCB would need upstream fusing. The 121 kA at 415 V covers most industrial 400 VAC buswork without coordination headaches.
Physical fit and panel integration
Dimensions are 105 mm wide, 181 mm tall, and 86 mm deep — standard 3-pole MCCB footprint for DIN-rail or panel-mount. The 86 mm depth keeps it clear of shallow enclosure backplates. Rated insulation voltage is 800 V, covering 480/600 VAC systems with margin. Power loss is 13.5 W max, manageable for thermal budgeting in a sealed panel.
