Siemens 3NH3430 Fuse Holder NH3 630A 600VAC 3NH3430 Series

Siemens 3NH3430 is a one-pole, base-mount LV HRC fuse base for NH3 fuses, rated 630 A at 690 V AC (1000 V DC). It accepts flat-terminal NH3 fuse links and uses an M12 mounting screw for secure panel installation. Part of the SENTRON LV HRC fuse family, this NH3 size 3 base provides fast, reliable overcurrent protection in distribution panels and feeders, with a short-circuit rating up to 120 kA (Icu) at 690 V. Designed for DIN EN 60269-1 NH3 sizing, the 3NH3430 is intended to be paired with the corresponding NH3 fuse links and compatible enclosure hardware, making it a compact option for protecting motors, drives, and power feeds in industrial environments. This base does not include a switch; it is a dedicated fuse-base component that integrates into Siemens LV protection schemes for high-rupture-capacity fusing in panel-mounted installations.
