The Siemens SENTRON 3VA1116-4EE46-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 160 A across the ambient range from 40 °C up to 50 °C before the first derate step at 55 °C. That means in a standard 40 °C panel it holds the full 160 A without needing to oversize the frame — useful when you're stacking breakers in a warm enclosure.
The interrupting capacity runs 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. For a 415 V distribution board that's a solid 75.6 kA — enough to sit downstream of a main breaker without worrying about cascading failure into the bus.
The case measures 130 mm high, 101.6 mm wide, and 70 mm deep — a 4-pole MCCB that fits a standard SENTRON mounting footprint.
