Siemens SENTRON 3VA1116-5EF32-0AC0 — 160 A MCCB with TM240 Release
Its interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V — figures that define the maximum fault current it can safely clear at each voltage level without upstream coordination failure.
The 160 A rating holds flat from 40 °C through 50 °C, then derates to 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C. In a 50 °C panel — common for enclosed switchgear — you still get the full 160 A; above that, the thermal curve governs the usable load.
Panel Fit and Auxiliary Configuration
Dimensions are 70 mm deep, 76.2 mm wide, and 130 mm high — a standard 3-pole MCCB footprint that mounts on a DIN rail or panel-mount adapter in a distribution board. No undervoltage release, no shunt trip, no ground-fault monitoring, and no communication module are fitted on this variant — it is a straight line-protection breaker.
