Ratings to confirm before selection

The source specifications record Rated Fault Current: 10000 A, while an existing tag records 6kA. These may describe different test ratings and have not been treated as interchangeable breaking capacities. Other source tags record 240V/415V and Im=500A. The conductor entry 50-50 mm² and single-value operating/storage temperatures need confirmation from the device label or manufacturer data.

Have a suitably qualified electrician confirm application, ratings and required upstream overcurrent protection. No overload or short-circuit protection capability is inferred from the RCCB designation.
