The Siemens SENTRON 3VA1110-5EF32-0JH0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current at 40 °C, with an interrupting capacity of 187 kA at 240 V.
Interrupting and Continuous Ratings
Interrupting capacity drops with voltage: 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V. The continuous current holds at 100 A through 50 °C, then derates to 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. This thermal profile is typical for a 100 A frame — the breaker doesn't need to be oversized for a 40 °C panel ambient, but above 50 °C the derating curve governs the actual load it can carry.
Dimensions are 70 mm depth, 76.2 mm width, and 130 mm height — a standard 3-pole MCCB footprint that mounts directly onto a DIN rail or panel-mount base in a distribution board.
