Siemens SENTRON 3VA2110-6HN36-0JH0 — 100 A MCCB for Line Protection
This 3VA2110-6HN36-0JH0 is a SENTRON molded case circuit breaker (MCCB) from Siemens, rated for 100 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed up to the enclosure's internal temperature limit. Three poles, line-protection design, which means it's sized for feeder or main distribution duty in a panel, not motor branch-circuit protection. Interrupting capacity hits 242 kA at 240 V, 187 kA at 415 V, and still 121 kA at 500 V; that's enough for high-fault industrial services without cascading upstream breakers. Built-in shunt trip (STL) for remote emergency-off or undervoltage tripping, plus two auxiliary switches and one trip-alarm switch (HQ) for status feedback to a PLC or annunciator. No communication module onboard — this is a standalone breaker, not a power-metering or fieldbus device.
Panel Fit and Mounting
Dimensions: 181 mm tall, 105 mm wide, 86 mm deep. Standard MCCB footprint for a 100 A frame — fits a typical distribution panel's bolted mounting plate or draw-out cradle. Depth of 86 mm leaves room behind the gland plate for cable bending radius in a 200 mm deep enclosure. Power loss is 10 W max at rated load — negligible heat contribution for a 100 A breaker, but factor it if you're packing multiple units in a sealed stainless-steel cabinet.
