What this MCCB delivers
The Siemens 3VA2110-5JQ32-0CA0 is a 3-pole SENTRON molded case circuit breaker rated for line protection, carrying a continuous current of 100 A up to 50 °C and derating to 85 A at 70 °C. The interrupting ratings are 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 4.25 kA at 690 V — numbers that define the SCCR headroom for the panel's fault-current withstand. The 100 A continuous rating holds flat across 40 °C, 45 °C, and 50 °C ambient — no derating needed in a standard 40 °C panel environment. At 55 °C it drops to 96.25 A, and at 70 °C to 85 A. The integrated auxiliary trip is order code 3VA9608-0BB24. There is no trip indicator and no auxiliary contact block fitted from the factory.
Dimensions are 181 mm height, 105 mm width, 86 mm depth.
The ETU560 release supports adjustable I²t and I²t-off curves, which gives the panel designer room to achieve selective coordination with downstream breakers.
