FEATURES & FUNCTIONALITY : Woodward XI1S1R XI1S Relay

1A / Directional Earth Overcurrent for Solid Grounded Grids. 250 x In (half cycle), 100 x In for 1s, 30 x In for 10 s, 4 x In continuous. Characteristics: DEFT, NINV, VINV, EINV. . IEC 60255-1
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.

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

Benefits of the Professional Line : Woodward XI1E1 XI1E Relay

• Fast DIN rail mounting ⇛ easy and fast mounting
• Sealable plastic covers ⇛ safe (see if anybody has broken the seal)
• Super easy settings via front buttons ⇛ fast without computer
• LED and output relays fault indication ⇛ easy to find out what has happened
• Compact form factor ⇛ fits in small spaces
