MCB changeover
Low Voltage (LV) Switchgear System



Information
An MCB Changeover is an arrangement of two or more Miniature Circuit Breakers (MCBs) configured to manually transfer electrical load from one power source to another (such as Main Supply to Generator), while also providing overload and short circuit protection.
Manual source transfer
Overload and short circuit protection
Suitable for low current applications
Compact and economical solution
An MCB Changeover system typically consists of:
Two incoming MCBs (Main & Generator)
Mechanical or electrical interlocking arrangement
Common outgoing load connection
The interlocking ensures that both sources cannot be ON simultaneously, preventing back-feeding.
