MCCBs (Molded Case Circuit Breakers)
MCCBs (Molded Case Circuit Breakers) contain one main incomer & two smaller outgoing circuit breakers for overload & short-circuit protection.
Wiring
Wiring: Conductors are color-coded (R, Y, B, N, and E) and terminate neatly at MCCB terminals.
Busbar System
A partially apparent distribution busbar at the top allows devices to share power.
Surge Protective Devices (SPDs) or Relays
Modules with red and blue indication lights near the top MCCB are most likely SPDs or monitoring relays.
Metallic Enclosure
To ensure safety and accessibility, all components are firmly secured within a protective metal panel.
