The Siemens 3VA1132-3EF36-0DH0 is a 3-pole IEC frame 160 molded-case circuit breaker with a 25 kA interrupting capacity at 415 V (class N). That rating puts it on the line-side of a 160 A panelboard or a motor control center feeder — it clears a bolted fault up to 25 kA without the arc flashing upstream. The TM240 thermal-magnetic trip unit is set for a 32 A continuous rating (In), with the overload (Ir) adjustable from 22 to 32 A via a dial on the face. That adjustability means one SKU covers a range of downstream loads; you dial Ir to match the cable or motor FLA, not the other way around.
Clamp terminals accept copper or aluminum conductors without lug kits — speeds up panel wiring. The built-in undervoltage release (UVR) operates on 208-230 V AC, 50/60 Hz; it drops the breaker open when control voltage falls below about 85% of rated, which is standard for emergency-stop or power-loss sequences in IEC panels. Two auxiliary switches (HQ) plus a separate trip-alarm switch (HQ) give you status feedback for a PLC or a remote annunciator — one NO/NC pair for the breaker position, another for the trip event.
