Socomec NH2-400A-690V-45W Fuse Base

The Socomec NH2 fuse base is a high-current mounting base designed to accept NH2 fuses in industrial electrical installations, delivering reliable protection for feeders up to 400 A and 690 VAC. This base is built for DIN-rail integration in control panels, providing a compact, front-access interface that makes fuse replacement straightforward while preserving safe isolation and clear labeling. The unit draws about 45 W of power in normal operation, reflecting its built-in, low-loss design without compromising protection performance. With NH2 compatibility, it supports standard NH2 fuse cartridges used in heavy-duty distribution blocks and safety switches, enabling straightforward integration into multi-pole protection schemes. Typical use cases include motor control centers, distribution boards, and machinery feeders where high-current protection at 690 VAC is required, and where quick fuse changes and reliable visibility of the fuse condition are important. Key verified specs: rated current 400 A; rated operational voltage 690 VAC; base power consumption 45 W; NH2 fuse size and mounting variant compatible with NH2 fuses; designed for secure, code-compliant industrial protection assemblies.
