Metal surface-mounted distribution board, two-row. BF-O-2/48-C 113685

Professional modular distribution board for surface-mounted installations

The two-row surface-mounted distribution board BF-O-2/48-C is a complete solution for electrical installations in residential and commercial buildings. Designed for professional surface mounting on walls, it offers 48 module spaces (24 per row) in a robust steel enclosure.

Enclosure construction and materials

The enclosure, made of powder-coated steel in white RAL 9016, provides high mechanical resistance IK07 and long-term durability. The external dimensions of 555 × 460 × 150 mm allow for comfortable installation even in limited spaces, while maintaining an internal depth of 131 mm for easy cable routing.

The "flat" type design enables mounting directly onto the wall without the need to penetrate its structure. Metal doors with a three-point lock ensure secure access to the internal installation, and a transparent cover is not required due to the full functionality of the doors.

Terminal systems and compatibility

The distribution board is equipped with N/PE terminal blocks with the following cross-sections:

• Neutral conductor N: 2 × 25 mm² + 43 × 16 mm²
• Protective conductor PE: 2 × 25 mm² + 43 × 16 mm²

The DIN rail system allows for rapid mounting of modular devices according to individual installation needs. Screw terminals guarantee a secure connection for conductors of various cross-sections.

Operating parameters and safety

The device operates at a rated voltage of 415 V AC and a frequency of 50/60 Hz, providing an IP30 protection rating suitable for indoor installations. The operating temperature ranges from -5°C to +40°C, enabling operation in most construction environments.

Protection Class I (earthed) and a grounding resistance <0.1 Ω guarantee safe use in accordance with IEC/EN standards. The distribution board complies with the EMC directive and holds RoHS certificates.

Normative compliance and certificates

The product comes with full technical documentation confirming compliance with the following standards:

• IEC/EN 61439-1 (general requirements)
• IEC/EN 62208 (empty enclosures)
• IEC/EN 61439-3 (distribution boards)

Design verification includes corrosion resistance, thermal stability, and mechanical impact resistance IK07. Heat dissipation data is available for various mounting configurations according to the IEC 60890 standard.
