Why Choose the Rittal SV 3418.040 Bus-Mounting Fuse Base?
The Rittal SV 3418.040 is a 3-pole bus-mounting fuse base for D02-E18 fuse inserts, designed for reliable circuit protection within industrial power distribution systems. Featuring the Rittal Easy Connect design, it mounts directly onto busbar systems with a 60 mm centre-to-centre spacing and provides a compact, connection-ready solution for professional switchgear and panel-building applications.
Rated for a maximum current of 63 A, the SV 3418.040 supports a rated operating voltage of 400 V AC three-phase as well as 400 V DC configurations. Its bus-mounting fuse base is manufactured from fibreglass-reinforced thermoplastic polyester (PBT), while the contact hazard protection is manufactured from polyamide. The insulating materials provide fire protection corresponding to UL 94-V0.
The fuse base features box terminals for 1.5–16 mm² round conductors and is supplied as a pre-configured element ready for connection, including a cover plate, contact hazard protection and exterior connection clamps. Compatibility with 5 mm and 10 mm high busbars makes it a practical component for compact industrial power distribution assemblies.
