SENTRON 3VA1116-5EF42-0BC0 — 160 A 4-Pole MCCB for Line Protection
Thermal derating is minimal through 50 °C (still 160 A), then drops to 158 A at 55 °C and 150 A at 70 °C — so in a warm enclosure the full 160 A rating holds without margin loss under normal conditions.
The 4-pole width (101.6 mm) is standard for this frame class — verify panel cutout and busbar spacing before committing. The base switch variant is 3VA11165EF420AA0; this order code adds the UVR and aux switches as factory-installed options.
Breaking Capacity Across Voltage Tiers
Breaking capacity is voltage-dependent: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. The 415 V figure (121 kA) is the typical benchmark for 400 V class distribution — sufficient for most industrial service entrances. At 690 V the 17 kA rating limits application to lower-fault systems or requires upstream current limitation.
