Information
TeSys GS fuse switch-disconnector, 4 poles (4P), 50A/750V, to be used with NFC cylindrical fuse links size 14x51mm up to 50A, for motor applications up to 25kW@400V AC-23. To be equipped with an external front side or right-hand side mounting operating handle GS2AH (several models available). It provides screw terminals with 4P terminal shrouds, high short circuit current rating 100kA@400V. Add-on auxiliary contact modules GS1AM (front mounting), GS1AN (side mounting), GS1AF (top mounting for blown signaling with stricker fuses) can complete the assembly (to be ordered separately). Type aM and gG 14x51mm cylindrical fuse links without strickers DF2EA, DF2EN and with strickers DF3EA, DF3EN are available (to be ordered separately). Multi standards certified (IEC, Marine), Green Premium compliant (RoHS/REACh).
