Surface-mounted meter distribution board NRL-1F6 ZSZ with window and lock. space for 1-phase meter and 6 S-type protections. S.IP31 NRL 1F 6 ZSZ 4-260

Professional surface-mounted distribution board for single-phase installations

The NRL‑1F6 ZSZ surface-mounted meter distribution board is a complete solution for electrical installations requiring safe power distribution and electricity consumption measurement. Made of painted steel sheet with a thickness of 0,8 mm, it ensures durable protection of electrical equipment in residential, commercial, and service buildings.

Construction and device dimensions

The enclosure, with dimensions of 310 × 395 × 220 mm, has been designed as a compact, single-level construction housing one measuring module and six spaces for protective devices. The white color (RAL 9003) gives it an aesthetic appearance, fitting perfectly into modern interiors. The door, equipped with glass and a lock, allows both for monitoring the installation status and securing access to the equipment.

The IP31 protection rating protects against finger access to hazardous parts and against vertically dripping water, which is sufficient for standard indoor conditions. The mounting plate and one TH35 DIN rail facilitate the professional installation of modular devices.

Operating parameters and safety

The device operates at a rated voltage of 400 V and a current of up to 100 A, covering the needs of most domestic installations and small commercial facilities. An insulation voltage of 500 V and protection class I guarantee safe operation in industrial conditions.

The distribution board serves a multifunctional role - in addition to basic electrical power distribution, it enables the mounting of measuring equipment for energy consumption control and production process management. The single-phase meter space allows for precise monitoring of power consumption by a specific group of receivers.

Application and user benefits

Thanks to its universal design, the distribution board is suitable for both new installations and the modernization of existing electrical systems. The surface-mounted installation method eliminates the need for wall chasing, and the complete set includes all necessary accessories and a pair of keys for the door lock.

The solid construction made of painted steel ensures long-term resistance to corrosion and mechanical damage. The clear organization of the internal space facilitates servicing and any potential future expansion of the installation.
