Power factor correction capacitors are crucial components in electrical systems, helping to improve the power factor, reduce transmission losses, and stabilize voltage. However, under certain operating conditions, installing a reactor (inductor) in series with the capacitor becomes essential to protect the equipment and ensure the system operates efficiently. This article will help you understand when […]

An RCCB (Residual Current Circuit Breaker) is a safety device designed to protect people from electrical hazards. It immediately disconnects the power supply when a residual current (leakage current) exceeding the permitted limit is detected, typically caused by leakage through a person or to the ground. Applicable Standards for RCCB IEC 61008-1 specifies the general […]

An RCBO (Residual Current Circuit Breaker with Overcurrent protection) is an electrical safety device that integrates both residual current protection and overcurrent protection. It combines the functions of an RCCB and an MCB into a single unit. RCBOs protect people from electric shock hazards and safeguard equipment from overloads and short circuits. They are commonly […]

Type Test is a series of tests conducted on a representative sample of electrical equipment to verify that the product meets specified technical standards (such as IEC, ANSI, UL, TCVN, etc.). Type Testing is not performed on every mass-produced product but only on selected samples. If the tested sample meets the required standards, other products […]

An ACB (Air Circuit Breaker) is an air-type circuit breaker used to protect electrical systems from overloads, short circuits, and in some cases, phase loss, undervoltage, or leakage currents. ACBs can handle higher current ratings than MCCBs, typically ranging from 630A to 6300A, making them suitable for low-voltage electrical systems in industrial and commercial applications. […]
