Siemens SENTRON 3VA1116-4GE42-0AA0 — 160 A, 4-Pole MCCB
Breaking capacity sits at 121 kA at 240 V and 75.6 kA at 415 V, so it handles high-fault utility feeds without cascading upstream.
Derating and Thermal Management
Above that it starts to taper: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. Max power loss is 38 W — that's the heat you need to vent inside the enclosure. If the panel runs hot, size the bus and ventilation for the derated current, not the nameplate.
Breaking Capacity Across Voltages
The interrupting rating drops as voltage climbs: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V.
Dimensions are 130 mm tall, 101.6 mm wide, 70 mm deep — a standard 4-pole MCCB footprint that drops into most SENTRON panelboards and DIN-rail adapters.
