Distribution block Schneider Electric Prisma Plus G 4P 100A 28 terminals (LGY410028)

Schneider Electric Prisma Plus G distribution block, 4-pole rated for 100 A with 28 terminals, provides a compact and organized solution for consolidating conductors in control panels and switchgear. The unit is designed to group multiple incoming and outgoing wires onto defined poles, facilitating clearer wiring layouts and easier maintenance. Its configuration supports common industrial and commercial electrical distribution tasks where safe, reliable terminal grouping is required.

Advantages

The Prisma Plus G distribution block offers a stable current-carrying capacity of 100 A across four poles and accommodates up to 28 terminal connections, enabling efficient space usage in electrical cabinets. It supports neat conductor segregation and reduces the number of individual connection points on busbars or DIN rails. Built to integrate with standard panel layouts, the block helps simplify wiring runs and shortens installation time while ensuring consistent electrical contact and mechanical stability.

Suitable for

• Power distribution and branching inside industrial control panels and switchgear
• Grouping multiple conductor runs in commercial electrical installations
• Organizing output circuits from power supplies, contactors, or circuit breakers
• Applications requiring compact terminal grouping and clear wiring paths

When it may not be suitable

This distribution block is specified for 100 A current and four poles; it may not be appropriate for installations that require higher continuous current ratings or more poles. For environments that demand specialized terminal types, extreme vibration resistance, or integrated fusing and metering features, alternative components designed for those specific conditions should be considered.

Key specifications

• Number of poles: 4
• Rated current: 100 A
• Total terminals: 28
• Mounting: panel or DIN-rail compatible (check panel layout for compatibility)
• Intended use: electrical distribution and conductor grouping in control panels and switchgear

How to use

Install the distribution block in the panel according to the panel manufacturer’s layout and ensure secure mechanical fastening. Route conductors to the respective poles and tighten terminal clamps to the recommended torque values specified in the installation instructions. Maintain correct conductor sizes and insulation stripping lengths for reliable contact. After wiring, verify continuity and insulation resistance as part of commissioning and ensure all live parts are enclosed before energizing the system.

What to consider before purchase

• Confirm that a 4-pole, 100 A distribution block with 28 terminals meets your circuit and conductor count requirements
• Verify mechanical mounting compatibility with your panel or DIN-rail system
• Check conductor size range and recommended torque values in the technical documentation
• Ensure the block’s electrical rating aligns with your system’s voltage and current needs

Usage recommendations

Use appropriately sized conductors and follow the manufacturer’s torque and installation instructions. Group related circuits logically to simplify maintenance and label terminal groups for easy identification during service.
