AC circuit breaker is an essential safety device used in electrical systems to protect electrical circuits from excessive current flow due to an overload or a short circuit. AC Circuit breakers are typically used in residential, commercial, and industrial applications to maintain the safety and functionality of electrical systems.
AC mini circuit breakers (MCBs) are compact, modular protection devices designed for low voltage electrical systems. They are typically used in residential, commercial, and light industrial ,Backup Power System,Electric Vehicle Charging Stations and so on for the protection and control of electrical circuits.
Renewable Energy Systems: MCBs can be found in solar photovoltaic (PV) systems, wind turbines, and other renewable energy installations, where they protect inverters, charge controllers, batteries, and other components from overloads and short circuits.
Safety
AC Circuit breakers help prevent electrical fires and damage to electrical equipment by interrupting the flow of current in case of a fault.
Convenience
AC Circuit breakers can be easily reset after resolving the issue that caused the trip, unlike fuses that need to be replaced.
Selectivity
AC Circuit breakers can be designed to trip at different current levels, allowing for better coordination and isolation of faulty circuits in a system.
Reliability
AC Modern circuit breakers are designed to operate with high accuracy and minimal maintenance, ensuring the long-term protection of electrical systems.
