The Siemens SENTRON 3VA1096-3ED32-0KC0 is a 3-pole molded case circuit breaker (MCCB) rated for 16 A continuous current at 40 °C, with a thermal derating curve that holds 16 A up to 55 °C before stepping to 15 A at 60 °C through 70 °C. Its interrupting capacity reaches 75.6 kA at 240 V AC, 52.5 kA at 415 V, and 32 kA at 440 V — numbers that govern its selectivity and SCCR headroom in a distribution panel.
The 75.6 kA at 240 V is the highest short-circuit current it can safely interrupt at that voltage; at 690 V that figure drops to 7.5 kA. For a project engineer building a selective coordination study, those are the values that determine whether this breaker holds or trips ahead of downstream devices.
The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard SENTRON 3VA form factor that mounts on a DIN rail or directly to a backplate via screw terminals. The 3-pole footprint matches the existing cutout in most distribution boards sized for 125 A frame MCCBs.
