Circuit Breaker and its types

 What is a Circuit breaker?

In a nutshell, a circuit breaker is an electrical switch that is used to protect an electrical circuit from damage caused by a short circuit.

Join us for a comprehensive overview of circuit breakers. We will also introduce the types of circuit breakers and their applications.

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation.

Circuit breakers are made in varying sizes, from small devices that protect low-current circuits or individual household appliance, up to large switchgear designed to protect high voltage circuits feeding an entire city. The generic function of a circuit breaker, or fuse, as an automatic means of removing power from a faulty system, is often abbreviated as OCPD (Over Current Protection Device).

Different Types of Circuit Breaker

circuit breaker types are done in different categories, which we will name and explain.

  • Single-Pole Circuit Breakers

Single-pole circuit breakers are the most common types of circuit breaker in today’s homes. They are referred to as single-pole because in the case of a short or electric overload they are equipped to track the current of a single wire. Single-pole breakers are designed to handle 15 to 30 amps and provide the circuit with 120 volts.

  • GFCI Circuit Breakers

ground fault circuit interrupter circuit breakers (GFCI) are designed to avoid line-to-ground error. This is because there is an unsafe electrical path between a grounded element and an electrical current. GFCI breakers often have protection against an electrical short or overloaded current. Any electrical codes for house areas that may become watered, including toilets, laundry rooms, and outside areas, include these breakers. Read more

Introduction of electric motors and types

Image
  You've probably heard of electric motors by now. A critical piece in all electrical appliances. In this article, we will introduce electric motors in detail and examine its types, so stay tuned. An electric motor is a component that converts electrical energy into kinetic energy. Most electric motors are  electromagnetic -based. Most electric motors are rotary, but there are also linear motors. In a rotating motor, the moving part (usually inside the engine) is called the impeller or rotor, and the fixed position is called the station or stator. The motor consists of electric magnets wound on a frame. Although this frame is often referred to as armature, the term is often misused. Types of Electric Motor Electric motors may be classified by considerations such as power source type, internal construction, application and type of motion output. In addition to AC versus DC types, motors may be brushed or brushless, may be of various phase (see single-phase, two-phase, or three-...

Introduction and review of Suspension Insulators and Strain Insulators

Image
  In this article, we will have a detailed explanation and review of Suspension Insulators and Strain Insulators. Join us and read this article. First, we will introduce Suspension Insulators, and after reviewing it, we will submit Strain Insulators What is Suspension Insulators  ? The suspension type insulator consists of several insulation parts connected in series and forms a string. In suspension insulators, each porcelain discs is designed to work at 11 kV, and as the operating voltage increases, the number of discs in the string and in series increases as well. For example, the number of insulator discs required is 12 in 132 KV transmission lines.  Read More in Linquip What is Strain Insulators  ? According to  Wikipedia , A strain insulator is an electrical insulator designed to work in mechanical voltage (strain) to withstand the pull of a suspended electrical wire or cable. They are used in overhead electrical wiring to support radio...

Everything you should know about HVAC

Image
What is HVAC? What do you know about it? What is its use? In this article, we will take a closer look at HVAC, so join us to get the answers to these questions and any other questions about HVAC. The importance of HVAC Heating, ventilation, and air conditioning (HVAC) is the technology of indoor and vehicular environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of  mechanical engineering , based on the principles of thermodynamics, fluid mechanics and heat transfer. As was mentioned earlier, an  HVAC system  is intended for thermal control of areas as well as comfort for occupants. Temperature is factor that affects the performance and health status of many systems. Take the case of a server room temperature as an example for which high temperature adversely affects the system’s reliability and operation of the servers is a great source of heat ge...
