What this MCCB delivers
The Siemens SENTRON 3VA2010-5HN36-0KC0 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 the enclosure's thermal limit. Its interrupting capacity reaches 187 kA at 240 V AC, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3 kA at 690 V, covering high-fault service-entrance and distribution applications where SCCR headroom is critical for selectivity coordination. Built for line protection, this MCCB integrates a shunt trip (STL) and two HQ auxiliary switches, plus a voltage-trigger function — no undervoltage release, no ground-fault monitoring, no communication module. The 13.5 W maximum power loss stays manageable for standard panel layouts.
Panel fit and mounting
Dimensions are 105 mm wide, 181 mm high, 86 mm deep — a compact 3-pole footprint that fits standard Siemens SENTRON panel cutouts and busbar systems. The 86 mm depth leaves clearance for rear-connected cables or bus risers in typical 600 mm deep enclosures.
