This variant is configured for starter protection: the magnetic short-circuit pickup is adjustable from 5 to 15 times In (625–1875 A), and it ships without overload protection, relying on a separate overload relay in the motor starter circuit. The 3-pole form factor fits standard 160 A frame cutouts. The auxiliary switch (HQ) and trip alarm switch (HQ) provide remote status feedback for PLC or SCADA inputs — useful for fault logging in automated lines.","metaTitle":"Siemens 3VA1112-5MH32-0AF0 Circuit Breaker, 125A, 55kA @ 415","metaDescription":"Siemens 3VA1112-5MH32-0AF0 IEC frame 160 MCCB, 55kA breaking capacity @ 415V, 3-pole, TM120M trip, auxiliary & alarm switches.
