The circuit breakers and isolators serve a common purpose of circuit interruption. The primary difference between them lies in their behavior during faults in the circuit. In this article, let’s discuss the difference between a circuit breaker and an isolator. Isolator/ Disconnectors An isolator or disconnector, as the name indicates, is a switching or isolation … Read more
MCB – Miniature Circuit Breaker and RCBO – Residual Current Circuit Breaker with Overload Protection are circuit protection devices. These devices are commonly used in low-voltage power distribution and can be seen in distribution boards in homes, offices, commercial buildings, etc. Difference between MCB and RCBO MCB – Miniature Circuit Breaker RCBO -Residual Current Circuit … Read more
Before getting into the topic, we have to keep two points in mind.1. Conventional Current flow. (The way Current is said to flow historically)2. Actual current flow. (The way Current actually flows). By definition, current is the flow of charges, basically electrons. It is said to flow from a point of higher potential to lower … Read more
PLC – Programmable Logic Controller Programmable logic controllers are electronic devices used to control a process. It consists of CPU; Input and output devices, power supply, communication and redundancy units. PLCs are preprogrammed based on their application and put into operation. A PLC accepts inputs from the field, process the input based on the programming … Read more
Motor Protection Circuit Breakers and Moulded Case Circuit Breakers and are devices used to open and close a circuit manually and interrupt the circuit automatically on the occurrence of faults. MPCB and MCCB are used to protect against overload and short circuits. The application of Motor Protection Circuit Breaker is entirely different from that of … Read more
RCCBs and RCBO are residual current protection devices. Residual current protection is achieved by monitoring the flow of current in the line and neutral. In a healthy circuit, the current flow through the line will be equal to the return flow in the neutral. In the case of any abnormalities, this return flow may not … Read more
Difference between MCCB and RCCB MCCBs and RCCBs are circuit protection devices with two different application. When the former protect against overload and short circuit, the later protects against Residual currents and electric shock. MCCB- Molded Case Circuit Breakers Moulded Case Circuit Breakers protect against overcurrent and short-circuits only unless otherwise, they have inbuilt residual protection. MCCBs trip as … Read more
MCBs and MCCBs have commonly used circuit protection devices. These devices provide protection against overcurrent and short circuits. In this article, let us discuss the difference between MCB and MCCB. Overview of MCB: These are thermal / thermo-magnetic devices Provides protection against overcurrents and short circuits. Available up to 100A and have a maximum short … Read more
Contactors and relays are electrically operated switches used for the control and switching of loads. The difference between them primarily lies in the load current that they can handle, where they are used, and how they are used in a circuit. This article can give you a clear picture of the difference between contactor and … Read more
The most important difference between soft starters and VFDs is the role they play in motor control. Even though they have a similar principle of operation, they are different. This article will help you understand the difference between soft starters and VFDs. Why use VFDs and soft starters? When started by a direct-on-line starter, a … Read more
