The electrical management system (EMS) will collect data for monitoring and/or control purposes from various breakers within the switchboards.
There are different types of breakers, and each has specific properties and functions that suit it to specific situations. An effective monitoring system integrates with breakers and is capable of collecting various data from them. The data can then be interpreted for fault detection and optimization.
These represent the typical and most common types of breakers employed in most systems:
- Vacuum Circuit Breakers (VCB): Utilizing vacuum interrupters, VCBs are primarily used in medium-voltage applications. They offer fast arc extinction and long service life, making them ideal for high-performance, maintenance-friendly environments.
- Air Circuit Breakers (ACB): ACBs are used in low-voltage power distribution systems and employ air as the arc-quenching medium. They provide high current interrupting capacity and are often deployed for main incomer protection in low-voltage panels.
- Moulded Case Circuit Breakers (MCCB): MCCBs offer compact, reliable protection for low-voltage circuits. Typically used in sub-distribution boards, they combine thermal and magnetic protection features and are suitable for a wide range of current ratings.
- Fuse Switches (FS): Fuse switches integrate a fuse within a manually operated switching device, providing simple but effective circuit protection. They are commonly used where motorized operation and auxiliary feedback are not required.
