Its headline breaking capacity is 55 kA Icu at 415 V (breaking capacity class M), which means it can safely interrupt fault currents up to that level at the panelboard — essential for high-fault installations where upstream coordination demands a robust interrupting rating. The TM240 overload protection is adjustable from 700 A to 1000 A (In=1000 A), and the short-circuit pickup (Ii) is fixed at 5 x In. That fixed magnetic setting suits motor or transformer feeders where the inrush is predictable and a higher instantaneous threshold avoids nuisance tripping on start-up. It ships with a nut keeper kit, two auxiliary switches (HQ), and one trip alarm switch (HQ) pre-installed — so the signaling and alarm contacts are ready for integration into a PLC or annunciator circuit without ordering separate add-on blocks. ## Lifecycle and sourcing reality For a BOM line requiring this exact interrupting rating and trip configuration, the part can be sourced and quoted to order. Availability and current pricing are confirmed at quote time through independent distribution. ## Deployment context This 3VA1 frame breaker mounts on a DIN rail or can be fixed-panel installed — the nut keeper kit secures it in place for high-vibration environments like generator or transformer feeder panels. The auxiliary and alarm switches (HQ) provide status feedback for remote monitoring or safety interlocks.","metaTitle":"Siemens 3VA1510-5EF32-0AH0 3VA1 IEC Frame 1000 Breaker, 55kA","metaDescription":"Siemens 3VA1510-5EF32-0AH0 circuit breaker, 3VA1 IEC frame 1000, 55kA Icu @ 415V, 3-pole, TM240 overload 700-1000A, Ii=5xIn.
