LDB4J

Overview

The Hoffman LDB4J is a NEMA 1 rated indoor distribution board designed for commercial and industrial electrical systems. Constructed from cold-rolled steel with a baked-on enamel finish, it provides secure protection for circuit breakers and busbars. The unit features a hinged door with a key-operated lock and includes provisions for mounting standard DIN-rail components or panel-mounted devices. It supports single-phase power distribution with integrated neutral and ground bars.

Feature Summary

• Hinged door design with key-operated locking mechanism for secure access
• Cold-rolled steel construction with durable baked-on enamel coating
• Integrated neutral and ground bars for simplified wiring connections
• NEMA 1 rating suitable for indoor dry location environments

Applications

• Commercial building electrical distribution panels
• Industrial control centers requiring NEMA 1 protection
• Lighting distribution boards in office facilities
• Equipment power supply units in manufacturing plants

Procurement Notes

Verify the specific voltage and amperage ratings required for your application against the official Hoffman Enclosures datasheet before ordering. Confirm that the enclosure dimensions match your spatial constraints and that the included hardware meets local electrical codes. Ensure the selected model corresponds to the exact phase and pole configuration needed for your system design.

Selection Notes

Select this model based on its NEMA 1 rating for indoor use where environmental protection is limited to dust and light contact. Consider the internal layout requirements for breaker spacing and wire bending space. Evaluate the need for additional knockouts or cutouts if custom wiring paths are necessary beyond the standard configuration provided by the manufacturer.

Part Context

This distribution board belongs to Hoffman's line of standard indoor enclosures designed for general-purpose electrical distribution. It is part of a broader family of NEMA 1 products offering various sizes and configurations to accommodate different load capacities and physical footprint requirements within commercial and industrial settings.

Replacement Considerations

Consult official Hoffman Enclosures documentation for direct replacement part numbers. Verify compatibility with existing mounting structures and electrical connections when substituting older models. Ensure any replacement maintains the same NEMA rating and material specifications for consistent performance.
