The Siemens 3VA2110-5JP32-0JL0 is a SENTRON molded case circuit breaker (MCCB) designed for line protection in industrial power distribution. It carries a continuous current rating of 100 A across the full ambient temperature range from 40 °C to 70 °C, with no derating needed up to that ceiling (–). Three-pole construction with a maximum breaking capacity of 187 kA at 240 V, stepping down to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. That SCCR headroom covers most industrial fault-current scenarios up to the 500 V level; at 690 V the interrupting rating drops sharply, so verify coordination if the service voltage exceeds 500 V.
Auxiliaries and communication
Factory-fitted with two auxiliary switches, one trip alarm switch, and one electrical alarm switch (HQ type) plus a shunt trip (STL) release. The communication function allows integration into a higher-level monitoring or control system — useful for remote trip indication and load management in automated lines. Power loss is 10 W maximum. The operating temperature range spans -25 °C to 70 °C; storage from -40 °C to 80 °C. The dimensions — 86 mm depth, 105 mm width, 181 mm height (–) — fit standard panel cutouts for this frame size.
