CB-Class Automatic Transfer Switch — 630–1600 A
The CB-class (Circuit Breaker) automatic transfer switch uses two mechanically and electrically interlocked circuit breakers to switch between normal and emergency sources. Rated 630–1600 A, it provides source transfer with full short-circuit protection from the circuit breakers themselves, in a compact and cost-effective arrangement for commercial and industrial standby power.
Applications
Commercial buildings and retail complexes
Industrial plants with standby gensets
Residential and utility standby power
Fire pump and life-safety power circuits

- Frequently Asked Questions
What is the difference between CB-class and PC-class ATS?
CB-class uses two circuit breakers as the switching and protection devices, while PC-class uses an integrated switching mechanism rated to withstand short-circuit current on its own. CB-class is generally more cost-effective; PC-class is preferred for very high ratings and critical loads.
Can a CB-class ATS be used for fire pump circuits?
Yes, CB-class ATS is commonly applied to fire pump and life-safety circuits where the circuit breakers provide the required short-circuit protection.
