Siemens 5SN7206-0KA30 2-Pole Circuit Breaker With Auxiliary Contact

Siemens 5SN7206-0KA30 is a 2-pole circuit breaker with an integrated auxiliary contact, configured for a 6 A nominal current rating. It protects two conductors from overcurrent while providing a built-in auxiliary contact to signal its status to control circuits or interlock logic, enabling simple remote monitoring and interlocking in automation systems. This model is used in industrial control panels and equipment where two-channel protection is required and a signaling path is beneficial for PLCs or safety interlocks. The 5SN7206-0KA30 configuration combines primary protection with signaling in a single device, simplifying wiring and reducing the need for separate auxiliary blocks in Siemens-based installations. Operators and technicians rely on this arrangement to obtain real-time feedback on breaker state for status monitoring, fault indication, or safe-start interlocks in motor control and automation applications. By pairing a 6 A protective capacity with an auxiliary contact in a single unit, this Siemens part supports compact, integrated protection schemes in panel builders and OEM equipment that require dependable overcurrent protection plus signaling for automation logic.
