The 'FTFM' designation means the breaker ships with fixed thermal and fixed magnetic settings — no adjustment dials to walk off over time, which is exactly what you want in a DC Power OEM build where the protection curve stays locked to the load. Breaking capacity class H means this 3-pole unit can interrupt 70 kA at 415 VAC. If you're coordinating with an upstream fuse or breaker, the 70 kA Icu gives headroom for selectivity without stepping up to the next frame size. The nut keeper kit in the description flags this as a DC Power OEM-tailored variant. That custom suffix (-ZD00) locks in a specific accessory and factory configuration. Fixed Ir=125 A and Ii=10 x In (1250 A magnetic pickup) means this breaker is set for a load that draws around 100-110 A continuous — motor feeder, large UPS input, or a distribution subfeed. The thermal-magnetic TM210 curve provides inverse-time overload protection and instantaneous short-circuit response. No thermal adjustment means one less thing to verify during commissioning. The 3-pole construction and IEC frame 160 footprint mount on standard DIN rail or panel-mount via the 3VA1 base. At 125 A, you're in the range where panel builders typically use box lugs or busbar adapters — verify the termination kit matches your cable or busbar size before the install.","metaTitle":"Siemens 3VA1112-6ED32-0AA0-ZD00 Circuit Breaker, 125A, 70kA","metaDescription":"Siemens 3VA1112-6ED32-0AA0-ZD00 circuit breaker, IEC frame 160, 3-pole, 125A, 70kA breaking capacity @ 415V.
