What this MCCB delivers
The Siemens SENTRON 3VA2010-6HN36-0JC0 is a 3-pole molded case circuit breaker rated for 100 A continuous current at 40 °C, with an interrupting capacity of 242 kA at 240 V and 187 kA at 415 V — numbers that put it squarely in the high-fault-current class for industrial main feeders and large sub-distribution boards. The ETU350 electronic trip unit provides adjustable overload and short-circuit protection curves, letting you coordinate selectivity downstream without sacrificing speed on a hard fault. A built-in shunt trip (STL) allows remote tripping from an emergency-stop circuit or a PLC digital output, and the two HQ auxiliary switches give status feedback to the control system.
Thermal derating and panel fit
The 100 A rating holds flat from 40 °C to 50 °C, then derates linearly to 85 A at 70 °C — a curve that matters when this breaker sits in a warm switchgear cubicle alongside other heat sources. The 86 mm depth and 105 mm width fit standard Siemens SENTRON mounting patterns; the 181 mm height leaves clearance for the shunt trip wiring and auxiliary switch harness. No phase-failure detection or ground-fault monitoring is built in, so external modules handle those functions if the application requires them.
