SENTRON 3VA2110-5JQ32-0HL0 — 100 A MCCB with 187 kA Interrupting Capacity
The Siemens SENTRON 3VA2110-5JQ32-0HL0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a full-scale current of 100 A with an initial trip setting of 20 A. Its interrupting capacity reaches 187 kA at 240 VAC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — figures that define the fault-current headroom available for panel coordination studies. The breaker maintains its 100 A rating across the full ambient range from 40 °C to 70 °C with no derating, a useful characteristic when the MCCB is installed in a crowded enclosure where internal temperatures run high. Power loss is capped at 10 W maximum.
Integration and Mounting
The 3VA2110-5JQ32-0HL0 occupies a 105 mm width, 181 mm height, and 86 mm depth footprint — dimensions that govern panel layout and bus-bar takeoff spacing. It carries a shunt trip release (STL) plus a complement of two auxiliary switches, one trip alarm switch, and one electrical alarm switch (HQ configuration), providing status feedback for PLC or SCADA inputs. A communication function is built in, supporting integration into higher-level monitoring schemes without an external adapter module.
Environmental and Compliance
Operating temperature range spans -25 °C to 70 °C; storage range extends from -40 °C to 80 °C. The breaker includes a trip indicator and a voltage trigger for remote signaling.
