The Siemens SENTRON 3VA1096-3ED32-0DA0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, with a continuous current of 16 A up to 55 °C and 15 A at 70 °C. Its TM210 thermal-magnetic overcurrent release handles overload and short-circuit protection without a separate trip indicator. The 75.6 kA breaking capacity at 240 V AC means it can safely interrupt a fault current of that magnitude, keeping downstream equipment and panel wiring intact during a bolted short. Breaking capacity drops to 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 500 V and 690 V — the standard derating curve for a 16 A frame. The insulation voltage is rated 800 V, so it's suitable for 480 V and 600 V class systems with headroom. An undervoltage release (UVR) is built in, letting you trip the breaker on loss of control voltage — common for emergency-stop circuits or undervoltage protection on motor feeders.
Panel fit and mounting
The 3VA1096-3ED32-0DA0 measures 70 mm deep, 76.2 mm wide, and 130 mm tall — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without re-drilling. Power loss is 13.1 W maximum, so ventilation in a sealed cabinet is manageable; just don't crowd it against other high-dissipation devices. The operating range is -25 °C to 70 °C, storage from -40 °C to 80 °C.
