The Siemens SENTRON 3VA2110-5JQ32-0CH0 is a 3-pole molded case circuit breaker rated for a full-scale current of 100 A, with an adjustable thermal-magnetic trip range from 150 A minimum to 1 200 A maximum. Its interrupting capacity reaches 187 kA at 240 V, dropping to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — figures that define its fault-clearing envelope across common industrial voltage levels.
Thermal performance and panel fit
Maximum power dissipation is 12.5 W, manageable in a standard enclosure without forced cooling. The 86 mm depth, 105 mm width, and 181 mm height (3.39 × 4.13 × 7.13 in) fit a compact DIN-rail or panel-mount footprint; verify gland-plate clearance for the UVR and communication wiring. The undervoltage release (UVR) triggers a trip on loss of control voltage — specify the coil voltage separately. A trip indicator confirms the breaker has opened on fault, aiding fault isolation during commissioning or MRO rounds.
