The thermal element provides overload protection, though the description explicitly notes this variant is configured without overload protection, relying instead on the upstream starter's overload relay. The magnetic short-circuit pickup Ii is adjustable from 5 to 15 times In (625 A to 1875 A), letting you dial in the instantaneous trip threshold to coordinate with the motor inrush and downstream cable protection. ## Auxiliary and alarm switching Factory-fitted with one auxiliary switch (HP) and one trip alarm switch (HP). The auxiliary signals the breaker's open/closed position to a PLC or status lamp; the trip alarm latches on a fault trip (short-circuit or overload) and stays closed until manually reset — essential for remote fault annunciation on an unattended line. ## Connection and panel fit Terminated via clamp connections — box-type lugs that accept aluminum or copper conductors without compression lugs.","metaTitle":"Siemens 3VA1112-5MH36-0AG0 Circuit Breaker, 55kA @ 415V, 125","metaDescription":"Siemens 3VA1112-5MH36-0AG0 circuit breaker, IEC frame 160, breaking capacity class M, Icu=55kA @ 415V, 3-pole, In=125A.
