The Siemens 3VA1116-5EE32-0KC0 is a SENTRON molded case circuit breaker (MCCB) designed for line protection in distribution panels. It carries a 160 A continuous rating at 40 °C and a 187 kA interrupting capacity at 240 V AC — that is the short-circuit current it can safely clear without welding contacts or rupturing the case, which is the figure that governs SCCR coordination downstream.
Ratings and what they mean for fit
Three poles, rated insulation voltage 800 V. The 160 A rating holds from 40 °C through 50 °C; it derates to 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. If your panel ambient runs above 50 °C, that derating curve is what decides whether this frame size works or you step up to the next amp rating. Breaking capacity drops as voltage rises: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V. For a 480 V panel (common in North America) the relevant figure is the 440 V rating — 75.6 kA — which covers most industrial service-entrance requirements. At 690 V the 17 kA rating means this breaker is suited for secondary-side distribution, not main incoming. This variant includes a shunt trip release (STL) for remote tripping, and two auxiliary switches (HQ) for status feedback to a PLC or annunciator. No undervoltage release, no ground-fault monitoring, no communication function. The shunt trip is what you order when a safety circuit or E-stop needs to open the breaker electrically.
Dimensions and panel fit
Width 76.2 mm (3 in), depth 70 mm (2.76 in), height 130 mm (5.12 in). That 76.2 mm width is standard for a 3-pole SENTRON 3VA frame — it drops into the same DIN-rail or mounting-plate footprint as the 3VA1112 and 3VA1110 siblings. No rewiring or bus-bar repositioning needed if you are swapping within the same family.
