What this MCCB brings to a panel
The Siemens SENTRON 3VA2110-5HN32-0DA0 is a 3-pole molded case circuit breaker rated for 100 A continuous current, sized to protect feeders or large branch circuits in industrial distribution panels. Its interrupting capacity hits 187 kA at 240 VAC and 121 kA at 415 VAC — numbers that tell you it can handle high-fault utility feeds without cascading upstream. The built-in undervoltage release (UVR) lets you drop the breaker on loss of control voltage, which is a standard requirement for emergency-stop or undervoltage protection schemes.
Dimensions and panel fit
The breaker measures 105 mm wide, 181 mm tall, and 86 mm deep. That width matches the standard SENTRON 3VA fixed-thermal-magnetic footprint — it occupies three 18 mm pole spaces on a DIN rail or panel-mount base. Depth of 86 mm means it clears most standard enclosure back-panels without interference.
