XI1ER1 XI1ER 1A / Directional Earth Overcurrent Protection relays

Product Description

The XI1E of the PROFFESIONAL LINE is an all-purpose protection against earth faults, used for electrical machines, lines and isolated or compensated systems; it is mainly used in radial networks. Very often the XI1E 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 XI1E-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, 67NsWoodward is an independent designer, manufacturer, and service provider of control solutions for the aerospace and industrial markets.
