The XI1S of the PROFFESIONAL LINE is an all-purpose protection against earth faults, used for electrical machines, lines and networks with solidly or sesistance-grounded neutral; it is mainly used in radial networks. Very often the XI1S can be found as backup protection at the central earthing point of the system. It detects all earth faults occuring in the system.

Relay variant XI1S-R with directional current sensing is a selective earth-fault protection and is normally used in ring systems, networks with parallel feeders and in complex meshed systems.

The XI1E is compliant with IEC 60255-1. Order Variants of the XI1E

• XI1E1 (1 A) ? ANSI 50Ns, 51Ns
• XI1E5 (5 A) ? ANSI 50Ns, 51Ns
• XI1ER1 (1 A) ? ANSI 50Ns, 51Ns, 67Ns
• XI1ER5 (5 A) ? ANSI 50Ns, 51Ns, 67Ns
