How do you choose the right site distribution cabinet for your project?
In the construction and industrial sectors, as well as for local authorities, safety on construction sites is an absolute priority. One of the key components in guaranteeing this safety is the electrical distribution cabinet. At Labérine, we understand the importance of a safe, reliable power supply for your projects. That's why we offer a range of custom-built distribution cabinets in a variety of power ratings, designed to meet the specific needs of each worksite. Our models come in three main power ratings: 63A, 125A, and 160A.
What is the purpose of an electrical distribution cabinet?
An electrical cabinet, distribution cabinet or site cabinet centralizes and protects the power supply on a construction site or industrial installation. It ensures safe distribution in any application requiring a temporary or permanent power supply.
By grouping the various electrical circuits and equipment in a single location, it centralizes, protects and manages the power supply. This not only protects the installation against electrical hazards, but also simplifies maintenance and power management operations.
The metering cabinet also plays a crucial role in protecting workers and equipment. It incorporates safety devices such as circuit breakers and differential switches, which prevent the risks of electrocution, overvoltage and short circuits. It also controls energy distribution and ensures a stable power supply, even under variable load conditions.
How does an electrical cabinet work?
The operation of an electrical cabinet is based on the integration of several key components that ensure the distribution and protection of electrical energy. When a power supply enters the cabinet, it is routed to various circuit breakers or fuses, which divide the energy into several separate circuits. Each circuit can then supply specific equipment, such as machines, lighting or power tools.
Circuit breakers play an essential role in constantly monitoring the flow of electricity in each circuit. In the event of an overload or short-circuit, they immediately interrupt the circuit concerned to prevent damage or accidents. Residual-current switches, meanwhile, detect current leaks and cut off the power supply if an anomaly is detected, protecting people from electric shock.
In short, the electrical cabinet distributes electricity via circuit breakers, which protect each circuit against overloads and short circuits. Residual-current switches cut off the power supply in the event of a current leakage, thus preventing electric shocks.
Where to place an electrical cabinet?
Placing a site cabinet is a crucial step in ensuring its functionality and safety. The ideal location must meet several criteria, including accessibility, protection from the elements, and compliance with current safety standards.
The electrical cabinet must be located in a place that is easily accessible to technicians and maintenance personnel. This facilitates inspection, maintenance and intervention in the event of a fault or problem.
If the distribution box is installed outdoors, it must be protected from the elements, humidity and dust. It must be located in a sheltered area, or fitted with a waterproof enclosure meeting IP (Protection Index) standards, guaranteeing adequate protection against splashing water and particles.
The meter cabinet must be installed in compliance with local and national electrical safety regulations. This includes respecting minimum distances from other installations, installing ventilation systems where necessary, and complying with directives concerning installation in specific environments, such as explosion-risk zones (ATEX).
Our range of distribution cabinets from 63A to 160A
63A distribution cabinets
63A distribution cabinets are designed to distribute electricity safely on construction sites. They can supply various types of equipment via 63A, 32A and 16A sockets. They incorporate all the protection necessary to secure the temporary installation and operators. These boxes, often supplied with tetraphase (5-pole) power, have an IP44 rating and are mounted on a tubular base. They are commonly used with rubber enclosures to supply power to various workstations.
125A distribution cabinets
We offer a wide range of 125A cabinets, with many customizable options. The basic version includes fuse protection (125A rating) with Mx coil, several switches, a differential switch, and various circuit breakers. A 5×50² input terminal block is also included. Our experts can propose a standard solution tailored to your needs, or create a custom cabinet if required. You can add differential circuit breakers, various types of sockets (Marechal, PowerSafe, etc.), and adapt outgoing and incoming terminals. We also offer grounding options and other customizations.
160A distribution cabinets
Our 160A cabinets are designed to meet the needs of various sectors. The basic version is equipped with protection devices, sockets and circuit breakers for a wide range of professional applications. These 160A distribution cabinets guarantee safe distribution of energy from the mains or a generator to various points. Each socket, whether single-phase or three-phase, has its own differential protection, enabling selective tripping in the event of an electrical fault.
In addition to its standard configuration, our 160A cabinets are fully customizable. You can add differential circuit breakers, specific outlets, and grounding options.
We offer cabinets to provide safe and reliable power for all your electrical installations and temporary worksites. We also offer you the possibility of fully customizing these distribution cabinets to suit your needs. For a personalized consultation, please do not hesitate to contact us.
