The Siemens SENTRON 3VA1116-4EF36-0KA0 is a 3-pole molded case circuit breaker (MCCB) built for line protection, rated at 160 A continuous at 40 °C with a TM240 thermal-magnetic overcurrent release.
Breaking capacity and what it means on site
This MCCB can interrupt 121 kA at 240 V and 75.6 kA at 415 V — numbers that tell you it's built for high-fault industrial panels, not light commercial. At 690 V it still clears 11.9 kA, so it handles the fault current a large motor or transformer can kick back.
Thermal derating and panel layout
Full 160 A rating holds from 40 °C to 50 °C, then drops gently: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. The 38 W maximum power loss matters for heat buildup inside a sealed cabinet; factor that into your thermal calc when stacking breakers side by side.
Physical fit and the shunt trip detail
Dimensions are 130 mm tall, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that drops into most SENTRON panelboards and DIN-rail adapters. Note there's no trip indicator and no undervoltage release on this variant; if you need a visual flag when it trips, spec a different option code.
