Siemens 3VA1 IEC frame 160 MCCB, breaking capacity class M, Icu=55kA @ 415V, 3-pole, starter protection TM120M, AM, In=100A, short-circuit protection Ii=5...15 x In, nut keeper kit, 4 auxiliary switches HQ.
Lifecycle stage is listed as current.
The nut keeper kit (included) retains the terminal screws during wiring — a time-saver on repetitive panel builds. Four HQ auxiliary switches are factory-installed, giving you status feedback for the open/closed/tripped positions without additional kit.
The 3VA1110-5MH32-0AE0 is rated Icu = 55 kA at 415 V AC, breaking capacity class M. That figure governs its ability to interrupt a short-circuit fault without damage to the switchboard.
No. The TM120M trip unit provides only magnetic (short-circuit) protection with an adjustable pickup Ii = 5...15 x In. Overload protection is omitted, so the breaker must be paired with a separate overload relay for motor branch circuits.
