The Siemens SENTRON 3VA2010-5HN36-0BL0 is a 3-pole molded case circuit breaker rated for 100 A continuous at 40 °C, with a maximum interrupting capacity of 187 kA at 240 V. It's designed for line protection in distribution panels, and the 100 A rating holds flat across the full ambient range from 40 °C up to 70 °C — no derating curve to chase for warm enclosures.
Interrupting capacity and selectivity
The 187 kA at 240 V drops to 121 kA at 415 V and 440 V, then to 75.6 kA at 500 V, and 3 kA at 690 V. That's a steep roll-off above 500 V — at 690 V the breaker is still rated, but the 3 kA ceiling means it's not the right choice for high-fault 690 V buswork unless the available fault current is known to be under that. For 240 V and 400 V class systems, the headroom is generous.
Built-in auxiliary and release options
This variant ships with an undervoltage release (UVR) and a complement of auxiliary switches: 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch HQ. That's enough for remote status and trip indication without adding external modules. The UVR is factory-fitted, so verify coil voltage compatibility with your control circuit before panel build.
Mechanical footprint and panel fit
Dimensions are 105 mm wide, 181 mm high, and 86 mm deep. The 105 mm width is standard for a 3-pole SENTRON frame — it occupies three 35 mm DIN spaces if mounted on a DIN rail, though the MCCB is typically bolted to a backplate. The 86 mm depth leaves clearance for rear-access busbars or cable glands in a standard 200 mm deep enclosure.
