Quick Summary
SV NH slimline fuse-switch disconnector from Rittal provides compact protection for 3-pole bar systems in switchgear and control panels. For engineers grappling with limited cabinet space and complex wiring, its slim profile and bolt-on M12 connections simplify mounting and field servicing. This device complies with IEC/DIN EN 60 947-3 testing and uses fire-rated polyamide (UL 94-V0), supporting safe operation in demanding environments. It also offers current transformer installation compatibility and clear fuse-monitoring pathways. By incorporating electronic fuse monitoring and an 185 mm centre-to-centre spacing, it helps reduce maintenance downtime, improves fault visibility, and accelerates panel assembly, while top/bottom cable outlets streamline terminations in dense distributions.

FAQs
The SV 9677.115 is designed for NH size 1 configurations and uses a bolt M12 connection with top and bottom cable outlets. For installation, align the device on the bar system with 185 mm spacing, secure with M12 bolts, connect conductors within the 6–240 mm² range, and ensure the current transformer installation path remains clear for monitoring access.
This unit is a 3-pole fuse-switch disconnector rated for 400 V (3-phase) and up to 250 A. It features a bolt M12 connection, top/bottom cable outlets, and is designed for 185 mm centre-to-centre spacing on NH size 1 busbar systems, with conductors ranging from 6 to 240 mm².
Yes. The SV NH slimline fuse-switch disconnector is specified for current transformer installations and includes a layout that accommodates CT wiring paths. Its electronic fuse monitoring supports real-time status checks essential for CT-connected protection schemes in control panels and switchgear.
The device undergoes IEC/DIN EN 60 947-3 testing and uses a fire-rated polyamide housing with UL 94-V0 compliance. These standards support safe operation and regulatory alignment in industrial environments, while the 3-pole protection and 185 mm spacing suit panel and busbar system requirements.
Electronic fuse monitoring provides real-time fault visibility, reduces troubleshooting time, and minimizes unplanned downtime. For OEMs and maintenance teams, this translates to faster diagnostics, smoother CT installations, and improved overall equipment availability in power distribution networks.
