The Siemens 3VA1116-5EE32-0JH0 is a SENTRON 3VA-series molded case circuit breaker rated for 160 A continuous current (Iu) across 40 °C to 50 °C ambient, with thermal derating starting at 55 °C (153.6 A) down to 144 A at 70 °C. Its interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 440 V — numbers that put it squarely in the high-fault-current class for industrial distribution and motor control center feeder protection.
What the SCCR ratings mean for selectivity
In practice, that SCCR headroom lets you place this breaker downstream of a transformer or generator bus with very high prospective fault current and still achieve full selectivity with upstream fuses or a larger-frame MCCB — no need to oversize the feeder breaker for the available fault current.
The 3VA1116-5EE32-0JH0 measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard 3-pole MCCB footprint that fits most enclosed panel layouts and DIN-rail adapters for the SENTRON 3VA family.
Temperature derating curve — plan the panel ambient
The breaker holds full 160 A rating from 40 °C up through 50 °C. Above that, the thermal-magnetic trip begins to derate: 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C.
