MCCB for line protection — 100 A frame, 242 kA interrupting capacity
The Siemens SENTRON 3VA2010-6HN36-0AC0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current at 40 °C through 70 °C, with no derating across that ambient range. Its interrupting capacity hits 242 kA at 240 V AC, dropping to 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V — a curve that tells you this breaker is built for high-fault industrial distribution, not branch-circuit light duty. The 800 V rated insulation voltage confirms it lives in 480 V or 600 V class panels with headroom. Designed for line protection, this MCCB sits at the incoming feed or a major subfeed in a switchboard or panel. The 86 mm depth, 105 mm width, and 181 mm height (–) fit the SENTRON 3VA modular footprint — it mounts on a DIN rail or bolts into a fixed cradle, with the 2 HQ auxiliary switches already integrated for status feedback to a PLC or annunciator.
Integration — panel fit and auxiliary wiring
The 86 mm depth is the critical dimension for enclosure depth — it clears most 200 mm deep wall-mount enclosures with room for rear cable entry. The 105 mm width and 181 mm height match the standard 3VA cutout; if you are retrofitting a panel that held a 3VA2116-5JP32-0AE0 (a 160 A frame), the 100 A frame shares the same mounting pattern and auxiliary switch slot, so it drops in without drilling new holes or re-terminating the bus bars. The 2 HQ auxiliary switches are wired for open/closed indication; they share the breaker's operating mechanism and do not require a separate power supply.
Selectivity and coordination — what the interrupting ratings mean
The 242 kA at 240 V is the maximum short-circuit current the breaker can safely interrupt at that voltage — it is not the continuous rating. For a 480 V panel, the relevant figure is 187 kA at 440 V; that gives you SCCR headroom for most industrial services. The 3 kA at 690 V is a steep drop, so if this breaker feeds a 690 V motor drive, verify the available fault current at that point in the distribution. The 100 A continuous rating holds flat from 40 °C to 70 °C (–), which means no derating in a hot switchgear lineup — a useful trait when the breaker is stacked near other heat sources.
