L&T Racking Interlock for C-Power Air Circuit Breaker

The "L&T Racking Interlock" is a safety feature commonly found in electrical switchgear equipment, particularly in circuit breakers and motor control centers manufactured by Larsen & Toubro Limited (L&T). This interlock mechanism is designed to prevent the insertion or withdrawal of circuit breaker drawers or modules while the circuit breaker is in the closed or energized position. It ensures that the breaker is properly disconnected from the electrical system before it can be removed or inserted, thereby reducing the risk of electrical hazards and ensuring the safety of personnel working on the equipment. The racking interlock typically consists of mechanical and/or electrical components that engage or disengage based on the position of the circuit breaker. When the breaker is closed, the interlock prevents the racking mechanism from being operated, effectively locking the drawer in place. Only when the breaker is open or in the disconnected position can the interlock be released, allowing the drawer to be inserted or withdrawn.
