A power distribution cabinet has many important parts. Each part helps you control electricity in your building. These parts also protect and watch over your power system. You need to know how these parts work. This helps keep your system safe and working well.
You will find circuit breakers inside every cabinet. Circuit breakers protect your building from electrical problems. If too much current flows, the breaker turns off the power. This stops damage from happening. You can reset most breakers after you fix the problem.
There are different types of circuit breakers. Each type works best for certain jobs. The table below shows common types and where you use them:
Circuit Breaker Type | Characteristics | Applications |
|---|---|---|
Miniature Circuit Breakers | Protects low voltage up to 100A; quick response; thermal or thermomagnetic operation. | Homes and businesses |
Molded Case Circuit Breakers | Handles high current up to 2500A; adjustable trip settings; plastic case for insulation. | Commercial and industrial use |
Vacuum Circuit Breakers | Uses vacuum to stop arcs; low maintenance; good for medium-voltage. | Medium-voltage applications |
Gas Circuit Breakers | Uses SF6 gas to stop arcs; great insulation; good for high strength needs. | Transmission lines and power stations |
Oil Circuit Breakers | Uses oil to insulate and stop arcs; works well in high-voltage. | High-voltage applications |
Air Circuit Breakers | Uses air to stop arcs; needed in low-voltage systems. | Low-voltage electrical systems |
Outlets let you plug in machines, lights, and other devices. Some outlets have safety covers to protect people. Some cabinets let you turn devices on and off in a safe order.
Tip: Always check the rating of your circuit breakers and outlets. This helps keep your system safe and stops overloads.
Meters show how much electricity you use. You can see real-time data about energy use. This helps you find waste and save money. Monitoring systems collect and study this data. You can use the information to make your system better and lower costs.
Meters and monitoring systems help you in many ways:
Metering cabinets let you watch energy use in real time. This helps businesses find problems.
They help collect and study data. This makes it easier to use energy wisely and save money.
By watching the whole energy system, you can find places to improve and use less energy.
Businesses that use real-time monitoring can cut energy costs by up to 20%.
Fixing phantom loads with good meter readings can save 5-10% on yearly bills.
Modern monitoring systems have advanced features. The table below lists some useful options:

Surge protection devices keep your system safe from sudden voltage spikes. These spikes can hurt equipment and stop work. You need surge protection for both AC and DC systems. Some devices protect your whole building from surges.
Mersen's surge protection devices are very important. They give strong protection against electrical surges that can hurt whole-house systems.
There are two main types of surge protection:
AC surge protection: Made to stop overvoltage in AC systems.
DC surge protection: Made for DC systems and their special needs.
Picking the right surge protection device is important. Look at voltage rating, discharge current, response time, and where you put the device.
Safety features in a power distribution cabinet follow strict rules. These rules keep you safe from electric shock, fire, and other dangers. The table below lists important safety standards:
Standard | Description |
|---|---|
IEC 61439 | Sets rules for design, building, testing, and how low-voltage switchgear and controlgear work. It protects against shock, fire, and other dangers. |
IEC 60529 | Sets how well cabinets keep out dust and water, like IP65 for outdoor use. |
IEC 60947 | Sets safety rules for low-voltage electrical equipment. It helps protect against shock and overloads. |
UL 508A | Sets safety rules for control panels. It focuses on short circuit and shock protection. |
NFPA 70 | Requires good grounding and installation to stop hazards. |
EN 60204 | Sets safety rules for electrical equipment in machines. It needs good grounding and labels. |
