Information
TeSys GS fuse switch-disconnector, 3 poles (3P), 250A/750V, to be used with type BS fuse links size B1-B3 up to 250A, for motor applications up to 132kW@400V AC-23. To be equipped with an external front side or right-hand side mounting operating handle GS2AH (several models available). Screw terminals to be equipped with upstream and downstream 3P terminal shrouds GS1AP43 (to be ordered separately), it provides high short circuit current rating 100kA@400V. Add-on auxiliary contact modules front mounting GS1AM (early-break and position signaling) can complete the assembly (to be ordered separately). Multi standards certified (IEC, Marine), Green Premium compliant (RoHS/REACh).
