What this 3VA MCCB does on the line
The Siemens SENTRON 3VA1116-6ED36-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous at 40 °C, with a TM210 thermal-magnetic overcurrent release that handles the long-time and short-time protection curve for feeder and distribution circuits. That means the protection curve is set at the factory for a 160 A frame; if your load profile needs a different long-time pickup or short-time delay, this isn't the variant.
Above that, it steps down: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C.
The 3VA1116-6ED36-0AA0 measures 70 mm deep by 76.2 mm wide by 130 mm high. The 76.2 mm width (3 inches) is the standard 3-pole MCCB footprint for a 160 A frame — it occupies three 25 mm DIN positions if base-mounted, or the same pitch on a mounting plate. The 130 mm height leaves room above for busbar connections or a shunt trip accessory (this variant has no undervoltage release or communication module).
