The Siemens 3VA1112-6EF32-0KC0 is a 3-pole IEC frame 160 molded-case circuit breaker in breaking capacity class H, rated to interrupt 70 kA at 415 V AC. Overload protection uses a TM240 thermal-magnetic trip unit with an adjustable Ir range of 88 A to 125 A, so you set the continuous current to match the downstream load. Short-circuit magnetic pickup (Ii) adjusts from 5× to 10× In — 625 A to 1250 A at the 125 A setting — letting you coordinate selectively with downstream branch breakers. A nut keeper kit is included for secure mounting in the panel.
The 3-pole footprint fits the 160 A frame size; verify busbar or cable lug clearance for the line and load terminals before finalizing the enclosure layout. The shunt trip coil draws from either a 220–250 V DC supply or a 208–277 V AC control circuit — no separate power supply needed if the panel already carries one of those voltages. Wire the auxiliary switches (HQ type) to the PLC or annunciator inputs for breaker status feedback.
