Product Description
A pluggable bushing current transformer for SENTRON 3NJ62/63 NH1 in-line switch disconnectors with fuses. The 200/5 A ratio with Class 0.5 accuracy meets legal-for-trade calibration requirements. Features a 15.2 mm bushing opening for 14 mm cables and a deeper 48 mm profile.
NH1 Pluggable CT Design
Designed as a direct plug-in accessory for NH1 fuse-type switch disconnectors. The 15.2 mm bushing opening accommodates cables up to 14 mm in diameter — optimized for installations with smaller conductor cross-sections. The deeper 48 mm profile provides additional internal clearance. No tools needed for installation or replacement.
