The LSIG protection profile covers long-time (overload), short-time, instantaneous, and ground-fault functions, with overload pickup adjustable from 100 A to 250 A. Short-circuit protection is set via Isd from 1.2 to 15 × In, with a fixed instantaneous pickup at 15 × In. Ground-fault protection is switchable, adjustable from 0.2 to 1 × In with a time delay of 0.05 to 0.8 s. The UVR ensures the breaker trips on loss of control voltage — standard for motor starter circuits where unintended restart after a power dip must be prevented. ## Deployment context The ETU860M trip unit communicates via the internal bus for power monitoring and parameterization — useful for coordinated motor protection schemes where selective coordination with downstream contactors and overload relays is required.","metaTitle":"Siemens 3VA2325-5MQ32-0DJ0 Circuit Breaker, 55kA @ 415V, 250","metaDescription":"Siemens 3VA2325-5MQ32-0DJ0 IEC frame 400 circuit breaker, 55kA breaking capacity at 415V, 3-pole, motor protection ETU860M, LSIG, In=250A.
