Electrical distribution board EFB Elektronik Box II 50DA

The EFB Elektronik Box II 50DA is a compact electrical distribution board designed to organize and protect circuit breakers and electrical connections in residential and commercial installations. With a compact footprint of 215 mm width, 76 mm depth and 215 mm height, this distribution board offers a space-saving solution for mounting on walls or inside service cabinets. The enclosure includes a secure lock mechanism and is constructed from durable materials to provide mechanical protection and clean cable routing for long-term use.

Advantages

This distribution board combines a small external size with practical interior space for arranging multiple modules and protective devices. The built-in lock enhances safety by restricting unauthorized access to circuit breakers and wiring. The durable enclosure material resists typical mechanical stresses encountered in installation environments and helps maintain a neat appearance over time. Its dimensions make it suitable for installations where space is limited while still allowing professional wiring and labeling.

• Small commercial premises and offices
• Utility closets and compact service rooms
• Replacement of older or damaged distribution boxes
• Applications requiring a locking enclosure for safety or access control

Key specifications

• External dimensions: 215 mm (width) × 76 mm (depth) × 215 mm (height)
• Enclosure type: wall-mount distribution board
• Locking mechanism: integrated lock for restricted access
• Construction: durable material suitable for indoor electrical installations

How to use

Mount the distribution board on a suitably prepared wall or inside a service cabinet at a recommended height that ensures access for inspection and operation. Install appropriate DIN-rail mounted circuit breakers and other modular devices inside the enclosure, following local electrical codes and safety standards. Route supply and load conductors through the provided cable entry points and secure them with appropriate terminals and cable management. After wiring is complete, close and lock the door to prevent unauthorized access. Commissioning and final connections should be performed by a qualified electrician.

Recommendations

Use the distribution board only indoors and in dry environments. Verify compatibility of all installed protective devices with the board's internal space and local regulations. Regularly inspect the enclosure, lock, and internal connections for signs of wear, corrosion, or loosening, and perform maintenance or replacement as required. Always follow applicable electrical codes and have installation and service carried out by qualified personnel.
