What this MCCB is and where it lands
The Siemens 3VA2110-5JP32-0CH0 is a SENTRON molded case circuit breaker (MCCB) rated for 100 A continuous current across its full ambient range from 40 °C to 70 °C — no derating needed in a warm panel. That 100 A holds steady at every temperature step the evidence lists, so you don't have to oversize for a hot enclosure. With three poles and a line-protection design, this MCCB is built for feeder and distribution circuits in commercial and industrial switchboards. It carries an undervoltage release (UVR) and a communication function, so it can talk to a control system and drop out on a loss of voltage without a separate relay.
Breaking capacity — what it means at your voltage
Rated breaking capacity changes with system voltage: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. That 187 kA at 240 V covers high-fault scenarios like a transformer secondary or a large motor control center bus. At 690 V the 3.7 kA figure is lower, so confirm your available fault current at that voltage before specifying.
Panel fit and integration notes
Dimensions are 86 mm deep, 105 mm wide, and 181 mm high. It mounts on a DIN rail or direct-panel bolt pattern typical of SENTRON 3VA frames. The auxiliary switch configuration — 2 auxiliary switches plus 1 trip alarm switch (HQ) — and the undervoltage release are built in, so no external add-on modules are needed for basic status feedback and voltage-loss tripping.
