Currently, industrial electrical equipment supplies are very diverse. In the article below, The tech will introduce some of the most commonly used materials and equipment in the industrial electrical industry for everyone to know.

The necessity of industrial electrical equipment

Industrial electrical equipment and supplies play a very important role in the operation and production of the industrial electrical industry. These include devices that perform tasks such as switching, regulating, controlling, protecting, and checking the operation of the power network system.

Commonly used industrial electrical equipment

Currently, industrial electrical equipment and materials are applied in many different fields to help:

  • Save human power
  • Reduce production costs.
  • The production line becomes more modern and professional.
  • Automatically closes and disconnects electrical circuits when there is a problem, protecting the motor of electrical equipment.
  • Limit the negative effects that endanger human health and life.

Summary of the most commonly used industrial electrical equipment

Industrial electrical equipment and supplies have a variety of types, but the most commonly used are:


Switchgear, also known as aptomat, circuit breakers, and fuses. This device is used to close and disconnect electrical circuits when the circuit is overloaded, short-circuited, or has a voltage drop. Thereby, protecting the electrical circuit is safe, and avoids unfortunate incidents.

Switching equipment in the circuit includes an MCB chip aptomat, an MCCB block aptomat, an ACB air circuit breaker, an RCCB leakage current circuit breaker, an RCBO overload and leakage protection circuit breaker, a lightning protection device, etc.


An inverter is a type of equipment that is capable of converting direct current into alternating current with adjustable frequency and voltage. Currently, there are types of inverters are DC inverters: 220V single-phase inverters, 220V 3-phase inverters, 380V 3-phase inverters, AC inverters, etc.

Protection relay

The relay can detect current abnormalities such as overcurrent, overvoltage, reverse power current, and too high or low frequency. On the market, there are many types of relays, such as overcurrent protection relays (OC), overvoltage protection relays (OV), over-frequency protection relays, and under-frequency protection relays. intermediate relay, latch relay, etc.

Commonly used industrial electrical equipment


A sensor is a device that detects and responds to input signals from the physical environment, such as humidity, pressure, light, temperature, motion, etc. Then, these signals were converted and readable on the screen. Depending on the needs of the user, there are different types of sensors, such as optical sensors, proximity sensors, level sensors, temperature sensors, pressure sensors, etc.

Electrical cabinet accessories

Electrical cabinet accessories are a group of equipment to ensure the operation of electrical cabinets, including ampere meters, current transformers, voltage transformers, multi-function electrical cabinet meters, electrical cabinet exhaust fans, power monitoring meters, dust filters, pillow supports, heat shrink tubing,…

Reactive power

Reactive power causes voltage drops and energy losses during power transmission. Therefore, reactive power compensating devices, such as capacitors and capacitor controllers, are generated to limit this phenomenon.

Some notes when choosing to buy industrial electrical equipment

When choosing to buy industrial electrical equipment, you need to keep a few things in mind:

  • Select materials that are compatible with electrical equipment. This is important because if something goes wrong, it can be easily replaced.
  • Strictly comply with standard requirements of electrical cabinets to be installed, such as capacity, voltage, operating temperature, humidity, etc.
  • If installing outdoors, you should choose materials that can resist UV, withstand wet environments, etc. to ensure durability and long-term use.

Above are the commonly used industrial electrical equipment materials that you should know and apply in life. I hope you got more useful information from this article. The tech is currently a reputable supplier of materials for manufacturing and assembling electronic components in the market.
