Quick Summary
Rittal SV 9666.560 NH Disconnector is a fuse-switch module for NH slimline enclosures. Engineers often struggle with wiring complexity and safe disconnection in compact panels. The design aligns with CE conformity and SIL-ready safety practices, while remaining compatible with commonly used IP-style enclosure protection concepts. Its 40x10 mm busbars and 185 mm centre-to-centre spacing reduce wiring errors and streamline installation in 12 x size 00 and 6 x size 1-3 configurations. With a footprint of 3 WU by 5 U in a 750 mm square, assembly parts are included to support scalable, compliant panel builds. This accessory simplifies maintenance and serviceability, translating to lower lifecycle costs.
