Thermal circuit breaker symbol

The thermal circuit breaker symbol is:

This symbol is used to represent a thermal circuit breaker in electrical diagrams and schematics. It is a combination of the symbols for a fuse and a circuit breaker, indicating that the device is designed to interrupt the circuit in the event of an overload or excessive heat.

The thermal circuit breaker is a type of overcurrent protection device that is designed to detect and respond to thermal overload conditions, such as those caused by excessive current flow or high temperatures. It is typically used in applications where a high degree of reliability and safety is required, such as in industrial control systems, power distribution systems, and electrical power generation and transmission systems.

The thermal circuit breaker symbol is often used in conjunction with other symbols, such as the symbol for a fuse or a circuit breaker, to indicate the type of overcurrent protection device used in a particular circuit or system.
