What this MCCB is and what it does
The Siemens SENTRON 3VA2010-6HN36-0DA0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current at 40 °C through 70 °C ambient — no derating needed across that entire span, which simplifies panel design in warm enclosures. Its interrupting capacity hits 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V. That 242 kA figure at 240 V tells you this breaker is built for high-fault locations — think main service entrance or downstream of a large transformer where available fault current is serious. The 800 V rated insulation voltage gives headroom for 480 V and 600 V class systems without creeping into coordination trouble.
Built-in undervoltage release
This MCCB ships with an undervoltage release (UVR) fitted — part of the basic switch assembly 3VA20106HN360AA0. That UVR trips the breaker if control voltage drops below a threshold, which is standard for emergency-stop chains or applications where a voltage dip must open the main disconnect. No communication module, no ground-fault monitoring, no trip indicator on this variant. It is a straight line-protection device — fit it where you need a high-interrupting MCCB with UVR and nothing else hanging off the aux bus.
Panel fit and dimensions
Dimensions are 105 mm wide, 181 mm high, 86 mm deep — a standard 3-pole MCCB footprint that drops into SENTRON panelboards and most DIN-rail or bolt-on mounting schemes without surprises. Maximum power loss is 16 W at rated current, so factor that into enclosure thermal calculations if you are packing several breakers in a sealed cabinet.
