What this breaker is and what the ratings mean for fit
The 3VA1180-4EE32-0AA0-ZD00 is a 3-pole IEC molded-case circuit breaker in the 3VA1 frame, rated In=80A with a TM220 thermal-magnetic trip unit (ATFM). The breaking capacity class S delivers Icu=36kA at 415V AC — that is the maximum fault current it can safely interrupt at that voltage, which determines whether it coordinates with downstream equipment without cascading failure. Overload protection is adjustable Ir=56A to 80A via the TM220 dial; short-circuit protection is fixed at Ii=10 x In (800A). That fixed magnetic threshold means it is suited for general distribution and moderate motor starting, not high-inrush transformer or capacitor loads where a higher Ii setting would be needed to avoid nuisance tripping.
Lifecycle and sourcing reality
The lifecycle stage is current. The -ZD00 suffix indicates a DC Power OEM variant with a nut keeper kit. Availability and pricing are confirmed at quote time against an RFQ through independent distribution channels.
