The Siemens 3VA1110-6EF36-0CA0 is a 3-pole IEC frame 160 circuit breaker rated 100 A continuous, with a class H interrupting capacity of 70 kA at 415 V AC. The TM240 thermal-magnetic trip unit gives adjustable overload protection from 70 A to 100 A (Ir) and short-circuit pickup (Ii) at 5 to 10 times In, so you can dial it in for motor or distribution duty without swapping the breaker.
What the ratings mean in the panel
Clamp connection terminals accept copper conductors without lug crimping, which speeds up panel wiring.
