Are circuit breakers with separate interrupting chambers for each phase known as individualized circuit breakers?

The assertion that circuit breakers with separate interrupting chambers for each phase are known as individualized circuit breakers is not accurate. In electrical engineering terminology, a circuit breaker designed with separate interrupting mechanisms for each phase is typically referred to as a "three-pole circuit breaker," where each pole serves one phase of the AC supply. Individualized circuit breakers would imply a design philosophy or capability that allows for independent operation for each phase, which is not the standard terminology used in the field.

The concept of circuit breaker operation primarily focuses on how they interrupt current and protect against faults, rather than on the specific configuration of interrupting chambers being classified as "individualized." Therefore, the statement is false, as the term "individualized" does not conventionally apply in this context.
