What this breaker does on the line
The Siemens 3VM1132-3EE36-0AA2 is a 3-pole IEC frame 160 molded-case circuit breaker rated 32 A continuous, with a 25 kA interrupting capacity at 415 V (class N). That Icu means it can safely clear a fault up to 25,000 A without welding its contacts or rupturing the case — sized for panelboard and distribution feeder duty where the available fault current is in that range. The TM220 thermal-magnetic trip unit gives you an adjustable overload band from 22 A to 32 A (Ir) and a fixed short-circuit pickup at 10× In (320 A). For a conveyor or pump panel, you set Ir to match the motor FLA or the downstream tap rating, and the magnetic instant clears a bolted fault before the cable insulation takes damage.
Lifecycle and sourcing reality
For a BOM freeze or a line-down replacement, the part is sourced to order against an RFQ. Availability and current pricing are confirmed at quote time through our independent supply network.
Panel fit and wiring
Mounts in a standard panel on a DIN rail or direct-screw pattern for the 160 A frame. The terminal connection accepts copper or aluminum conductors sized for the 32 A continuous load — no special lug kit needed for this rating. The ATFM designation covers the accessory suite: auxiliary contacts, shunt trip, and undervoltage release modules snap onto the breaker without increasing the panel depth. If you are wiring a safety circuit, the UVR can be tied into the E-stop chain to drop the breaker on a loss of control voltage.
