Siemens 3VA1116-4EF32-0DH0 — SENTRON MCCB, 160 A, 3-Pole, Line Protection
The Siemens 3VA1116-4EF32-0DH0 is a SENTRON molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 160 A at 40 °C (derated to 150 A at 70 °C per the thermal curve).
Breaking Capacity Across Voltages — Selectivity Planning
The 3VA1116-4EF32-0DH0 delivers 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.
Thermal Derating and Ambient Operating Range
Rated 160 A continuously at 40 °C through 50 °C, the breaker begins to derate above 55 °C: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. Maximum power loss is 40.5 W.
The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without requiring backpan modifications.
