Siemens 3VA1096-3ED32-0DC0 — SENTRON MCCB, 16 A, 75.6 kA IC
It carries a continuous current rating of 16 A at 40 °C, derating to 15 A at 60 °C and above — per the datasheet, the thermal curve holds flat to 55 °C, then drops by 1 A per 5 °C step. The interrupting capacity is 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V, with a floor of 7.5 kA at 500 V and 690 V.
What the interrupting ratings mean for panel coordination
At 415 V (common in industrial 400 VAC systems), the 52.5 kA rating still provides substantial headroom for most distribution panels. The drop to 7.5 kA at 500 V and 690 V means this breaker is not intended for 690 V main feeds unless the prospective short-circuit current is verified below that threshold.
Built-in undervoltage release — what it controls
The auxiliary switch complement is two HQ auxiliary switches, providing status feedback for the breaker position (open/closed/tripped) to a PLC or indication lamp. There is no communication function or ground-fault monitoring on this unit.
Panel integration — dimensions and mounting
The MCCB measures 130 mm height, 76.2 mm width, and 70 mm depth — a standard 3-pole SENTRON 3VA footprint that fits Siemens panelboards and distribution blocks.
