Air circuit breakers

Description

Two new air circuit breakers are required for the generator changeover panel at Ysbyty Ystrad Fawr Hospital. The existing ABB Air Circuit Breakers (ACB) have been inspected and found to have a structural crack in the breaker chassis. This represents a significant safety and reliability risk, as the chassis is a critical component providing mechanical integrity, alignment of internal contacts, and containment during fault conditions.
