The Siemens 3VA1180-6GF42-0AA0-ZD00 is a 3VA1 IEC frame 160 molded-case circuit breaker with a breaking capacity class H rating, meaning it can interrupt 70 kA at 415 VAC. The 4-pole design (three phases plus switched neutral) and the 100% N-conductor protection tell you it's intended for a 4-wire system where the neutral needs the same overcurrent protection as the phases.
The TM240 thermal-magnetic trip unit gives you adjustable overload protection (Ir = 56 A to 80 A) and fixed short-circuit protection (Ii = 5 to 10 x In). The ATAM designation means it's an adjustable thermal, adjustable magnetic unit, so both the long-time and short-time pickup points are field-configurable. The nut keeper kit included suggests this variant is prepped for a DC Power OEM application in China, but the base breaker is a standard 3VA1 frame that mounts in any Siemens-compatible panel.
