IEC 60269 400A DIN Rail Fuse Base 690V 120 kA Breaking Capacity

Product Summary

The BH-400 is a DIN rail type fuse base built for low voltage distribution systems in industrial and commercial electrical management. It is rated 690V and 400A, and its rated neutral links deliver a breaking capacity of 120 kA. Contact surfaces use tin-plated copper, while a flame retardant shell and IP30 protection support safe, 24/7 operation.

The base is designed to carry a matched fuse and mounts directly onto a DIN rail, complying with IEC 60269-1 and IEC 60269-2 as well as VDE 0636-1 and VDE 0636-2. It suits panel builders, switchgear assemblers and distribution board manufacturers who need repeatable isolation and short-circuit protection in one component.

Key Features

• 690V / 400A rating: carries heavy-duty low voltage distribution circuits where a 400A fuse base is required.
• 120 kA neutral link breaking capacity: high short-circuit withstand capability helps contain fault energy inside the base.
• Tin-plated copper contacts: deliver stable conductive performance and resist surface oxidation over service life.
• DIN rail mounting: installs into standard enclosures and pan assemblies for faster panel build and replacement.
• Flame retardant shell with IP30 protection: heat resistant and anti-aging, with a shock protection design suited to 24/7 duty.
• IEC 60269 and VDE 0636 compliance: supports approval documentation for export-oriented low voltage systems.

Technical Specifications

Models and Options

This listing documents model BH-400, a 690V, 400A DIN rail fuse base. If your distribution design needs a different configuration, share your circuit rating and rail layout with our sales team so the correct base can be confirmed against your project schedule. Detailed dimension drawings and the full catalogue are available on request.

Materials and Structure

The conductive path uses tin-plated copper contacts, selected for stable conductive performance in continuous duty. The housing is a flame retardant shell that is heat resistant and anti-aging, and the base is shaped for direct DIN rail mounting so it seats securely in fuse switch disconnector assemblies and low voltage distribution boards.

Applications

The BH-400 is applied in low voltage distribution systems across petroleum, chemical, metallurgical, power and construction industries, as well as commercial building electric management. Its typical function is power distribution and circuit protection, working together with a matched fuse under IP30 protection and a wide temperature range in 24/7 operation.

Customization

Requirements beyond the documented BH-400 configuration, including label marking and project-specific documentation, can be discussed with our engineering and sales team. Send your drawings or specification list and we will confirm what can be supported before quotation.
