The 3VA1125-6EE36-0AA0: This MCCB delivers 220 kA at 240 V AC, 154 kA at 415 V, and 121 kA at 440 V. That's selectivity headroom for the main distribution board. The 25 A rating holds flat from 40 °C through 50 °C, then derates to 24 A at 55–60 °C and 23 A at 65–70 °C.
The 3-pole body fits standard Siemens 3VA mounting feet — no adapter plate needed.
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
The 3VA1110-5EF36-0AD0 is a lower-current sibling in the same SENTRON 3VA family, but its trip rating and breaking capacity differ. Verify your load current and available fault current before substituting — the 3VA1125-6EE36-0AA0's 25 A TM220 release and 220 kA at 240 V are specific to this order code.
Both are 3-pole SENTRON 3VA MCCBs with the same mounting footprint (130 x 76.2 x 70 mm), so mechanical fit is identical. The wiring terminals and bus-bar spacing are the same family pattern. No panel rework needed for the enclosure fit.
