What you're getting
The 7SJ8011-5EB16-3FA0: SIPROTEC Compact 7SJ80 overcurrent time protection relay. Flush-mount housing, screw-type terminals. Powers from 60 VDC / 110 VDC / 125 VDC / 220 VDC, or 115 VAC / 230 VAC — covers both DC and AC floors in one unit. Front Ethernet port (DIGSI, not IEC 61850) and rear RS232 for DIGSI 4/modem. Four current inputs, 1 A or 5 A selectable. Three binary inputs, five binary outputs (two Form C), one live status contact.
Protection functions
This unit carries a full suite of ANSI protection functions: phase overcurrent (50/51), ground overcurrent (50N/51N), sensitive ground fault (50Ns/51Ns), high-impedance REF (87N), overload (49), trip circuit supervision (74TC), breaker failure (50BF), negative-sequence (46), undercurrent (37), lockout (86), flexible protection with current parameters, and inrush restraint. If your spec calls for auto-reclose or fault locator, this variant does not include them — skip this order code if that's a requirement.
