Why Choose the Cembre 2843711 DB500-11/1N Single Pole Distribution Block?
The Cembre 2843711 DB500-11/1N is a heavy-duty single-pole power distribution block designed for safe and organised high-current distribution within industrial control panels, switchboards and electrical distribution systems. Part of the professional Cembre DBLOCK series, it provides a compact method of dividing one incoming supply across multiple outgoing circuits.
With a rated operating current of 500 A, the DB500-11/1N is suitable for demanding applications where substantial power must be distributed reliably. Its incoming terminal accepts an 8 × 24 mm flexible busbar, while the outgoing terminals accommodate a range of conductor sizes for efficient connection to multiple downstream circuits.
The distribution block features a conductive body manufactured from electrolytically tin-plated brass, helping provide excellent conductivity, corrosion resistance and long-term connection stability. Its halogen-free Polyamide PA6.6 insulated body and transparent polycarbonate cover provide durable insulation, convenient visual inspection and IP20 protection.

Reliable High-Current Power Distribution
Power distribution blocks provide a central point for dividing a high-current incoming supply into several smaller outgoing circuits. This can reduce wiring congestion, eliminate unnecessary cable joints and help panel builders produce cleaner and more maintainable electrical assemblies.
The Cembre DB500-11/1N is designed specifically for installations using a flexible busbar input. Chamfered terminal entries, captive screws and direct-clamping connections make wiring straightforward, while the plated brass body helps maintain stable electrical performance throughout the service life of the installation.
Typical Applications
- Industrial control panels and switchboards.
- High-current power distribution cabinets.
- Motor control centres.
- Machinery and factory automation systems.
- HVAC control and power distribution panels.
- Building automation systems.
- OEM equipment and machine building.
- Industrial maintenance and panel upgrades.
