Overcurrents, including overloads and short circuits, can damage electrical circuits unless an MCB is present. With modular MCBs and the MCB select function, ensuring optimal safety and efficiency in electrical installations becomes straightforward and efficient. Because of their compact design, MCB is perfect for use in areas with premium space. Explore the Legrand eshop for various modular MCB options easily customisable for different circuit requirements and voltage levels. This article will teach more about circuit breakers, including how they function and the kinds of available ones.
● Thermoelectric component:
An MCB’s thermal element is a bimetallic strip that gets hot as current passes across it. It is possible to set the temperature at which a hybrid MCB’s thermal mechanism will trip. Normal operating circumstances and anticipated load dictate the fixed temperature. Because they don’t need as much current, modular MCBs used in homes usually have a lower set temperature than those in businesses and industries.
● Magnetic element:
Magnetic circuit breakers use solenoid coils to generate magnetic fields reacting to electric current. A precise current level triggers the trip of the magnetic mechanism. The magnetic field triggers the MCB by pulling on a spring-loaded trip lever, which releases the switch.
● Normal operation
The MCB allows current to enter the electrical circuit in a normal operating state. An MCB’s two contact points are those with the load and the incoming power source.
Various kinds of miniature circuit breakers
● Thermal MCBs:
When the temperature increases due to the current flowing through the circuit surpassing a specific threshold, thermal MCBs trip, a bimetallic strip is included, which can be bent to trip the breaker.
● Magnetic MCBs:
If the current passing through the circuit produces a magnetic force greater than a specific threshold, the magnetic MCB will trip. A solenoid pushes the trip spring, which in turn trips the breaker.
● Multi-Current Hybrid Breakers:
With hybrid MCBs, the best qualities of thermal and magnetic MCBs work together. They trip via a bimetallic strip and solenoid when the temperature rises, or the current generates magnetic force. The hybrid MCB’s thermal and magnetic tripping mechanisms allow it to respond quickly to overloads and short circuits. Hybrid MCBs are less prone to damaging electrical systems than thermal-type or magnetic modular MCBs.
● Applications
Unlike traditional circuit breakers, MCBs cut power to a circuit when the current is too high. Unlike ordinary circuit breakers, modular MCBs have unique properties and serve several applications. The MCB select feature simplifies circuit protection by allowing users to precisely match the current ratings to specific loads.
