This adapter kit is designed for DB retrofill air circuit breaker in DB switchgear. It allows existing switchgear door
Assembly adaptation with standard Emax 2 withdrawable air circuit breaker of the size indicated in Table A.
IMPORTANT !
Retrofitting allows an obsolete control and protection device to be replaced, but does not allow the ratings of the
original switchboard to be altered in any way.
The retrofitting kits are dimensioned and certified for the obsolete device performances which may be lower than the
new Emax 2 ratings. Consult ABB for further details.
Table A
The kit has been designed to preserve existing switchgear door and its operations functionality.

installation, operation, and maintenance manual of the Emax 2 circuit breaker document number
1SDH001000R0002. If optional auxiliary (secondary) circuits are required, refer to section 11.
