That 11.9 kA floor at 690 V is the figure to check against available fault current on 690 V systems — if your SCCR study shows higher, this breaker isn't the right node. Thermal derating is shallow: 160 A holds through 50 °C, drops to 158 A at 55 °C and 150 A at 70 °C. In a hot panel (say, 55 °C ambient), you lose 2 A — negligible for most loads, but a continuous 160 A load at 60 °C pushes the margin to 155 A. The undervoltage release (UVR) included in this code trips the breaker if control voltage drops, which is common for emergency-stop or safety interlock circuits. Dimensions: 130 mm high, 76.2 mm wide, 70 mm deep — standard 3-pole MCCB footprint for a 160 A frame. No communication module, so all status is local via the trip indicator (none on this variant) or auxiliary contacts (not included here).","metaTitle":"Siemens 3VA1116-3EF36-0CA0 SENTRON MCCB, 160 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1116-3EF36-0CA0 molded case circuit breaker, 160 A at 40 °C, 3-pole, 75.6 kA at 240 V.
