Overcurrent Relay, Current Production
The Siemens 7SJ8011-5EB90-1FA0 is an overcurrent protection relay, sitting under the Circuit Breakers, Fuses & Protection category in the Relays > Overcurrent Relays subcategory. It carries a 4 X I rating, meaning it is set to trip at four times the nominal current setting — a standard pickup for motor-start or transformer-inrush coordination where short-time withstand is needed before the protection clears a fault.
