SENTRON 3VA1116-5EE36-0AB0 — 160 A MCCB with TM220 Release
It is configured as a line protection device, meaning it is sized for feeder and main distribution protection rather than motor or generator protection. The interrupting ratings are 187 kA at 240 V, 121 kA at 415 V, 76 kA at 440 V, and 17 kA at both 500 V and 690 V — these are the fault currents the breaker can safely clear without damage to itself or downstream equipment. Front protection is IP40, suitable for enclosure mounting where tools are required to access the terminals.
Thermal Derating and Temperature Response
Above that, the continuous current must be derated: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. This is a standard thermal-magnetic characteristic — the bimetal element responds to both load current and ambient heat. In a hot panel near the top of a cabinet, expect the breaker to carry less than its nameplate 160 A before nuisance tripping becomes a risk.
The breaker measures 130 mm in height, 3 in (76.2 mm) in width, and 2.8 in (71.1 mm) in depth.
