FAQs
The SV 9344.020 is designed for mounting plate assemblies and fits standard Rittal mounting plates. It uses box-terminal connections with top or bottom cable outlets and clamps laminated copper bars up to 13x13 mm. Ensure the enclosure accepts 106 mm width and 194 mm height devices and that conductor sizes are within 4–95 mm² for round conductors.
Electronic fuse monitoring provides real-time visibility into fuse status, enabling early fault detection and faster fault isolation. This reduces unplanned downtime, supports predictive maintenance, and helps ensure that protective devices respond correctly during faults. The system remains compliant with IEC/DIN EN 60947-3 while delivering continuous operating safety in demanding industrial environments.
Yes. The SV 9344.020 is a 3-pole NH size 00 fuse-switch disconnector rated for 160 A at 400-690 V AC, making it ideal for 3-phase distribution in switchgear and control panels. Its mounting plate compatibility and box-terminal design simplify integration into standard industrial enclosures and modular power distribution architectures.
The unit is tested under IEC/DIN EN 60947-3 and features a UL 94-rated polyamide housing. It also aligns with ETIM EC001040 and ECLASS 8.0 code 27371401 classifications, supporting procurement workflows and compliance documentation for industrial projects.
The integrated fuse monitoring reduces surprise outages by signaling fuse status, aiding proactive maintenance. Its robust build and mounting plate compatibility streamline installation, lowering commissioning time and lifecycle costs. Expect improved plant uptime, safer fault handling, and easier scalability for future panel expansions.
