FAQs
Install the SV 9677.025 by aligning the unit with the 185 mm busbar spacing and securing it to the DIN rail or mounting frame per the Rittal installation guidelines. Use the box terminal for conductor connection and ensure the contact hazard protection cover is correctly positioned; follow the top/bottom cable outlet routing for clean, accessible wiring. Verify current rating and voltage compatibility (160 A, 690 V) before energizing.
The SV 9677.025 supports round conductor sizes ranging from 1.5 to 95 mm². This range accommodates most CT installation wiring and power feeds, enabling flexible routing from top or bottom outlets. Always secure conductors properly in the terminal to maintain electrical integrity and ensure torque specifications are met during installation.
Yes. The SV NH slimline fuse-switch disconnector is designed for current transformer installation, with 185 mm busbar spacing and a 3-pole configuration. Its compact footprint and accessible connection points simplify CT wiring, reduce installation time, and support safer, more maintainable CT circuits in control panels.
The unit complies with IEC/DIN EN 60 947-3 safety standards and uses UL 94-V0 flame-retardant material. These references support regulatory alignment for electrical protection devices and enhance safety margins in enclosed switchgear environments, aiding risk management and compliance programs.
The 50 mm wide by 670 mm tall footprint enables denser panel layouts and easier retrofits in compact cabinets. Top/bottom cable outlets streamline wiring, reducing routing time and simplifying service. The robust 3-pole design with CT compatibility also minimizes spare parts, contributing to lower total cost of ownership over the device lifecycle.
