As part of Schneider Electric's Square D GT family, the GT-918 monitors leakage current to support protective action in electrical distribution equipment and is used in industrial control panels and switchgear to enhance personnel safety and equipment protection. The GT-918 is listed alongside GT912 and GT930 models in the Square D product family, indicating its role as a dedicated ground-fault sensor within this lineup. Catalog entries for this family note a window size configuration such as 5 x 14 inches (127 x 356 mm) for ground-fault sensor assemblies, reflecting the physical form factors used across GT-series sensors. Bearing the Square D branding, this sensor should be installed following Schneider Electric installation instructions and aligned with applicable safety standards and electrical codes. As a current transformer-based sensor, the GT-918 interfaces with compatible Square D protection devices to form a complete ground-fault protection solution within protective relays and circuit-breaker assemblies.\u003c\/p\u003e\u003c\/div\u003e","brand":"Square","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46259059818730,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-012.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/schneider-electric-gt-918-ground-fault-sensor","provider":"GTG Hardware","version":"1.0","type":"link"}
