TEMPERATURE-CONTROLLED CIRCUIT BREAKER

摘要

The heating of the connected electric line (12) due to the line current (9) can directly be used as a criterion for switching-off by means of special heat flow clamp terminals (7), which are connected to the temperature-controlled circuit breaker in a thermally and electrically- optimized fashion for all conductor cross-sections used in the electrical installation. The short-circuit protection is ensured by selective clamp terminals for a wide range of typical applications. Since, in contrast to conventional circuit breakers with current- carrying bimetallic switches, it does not have its own-heat source, it is particularly suitable also to handle the problems in overheated switch cabinets.
