Siemens 5SN1706-0KA30 Miniature Circuit Breaker

Siemens 5SN1706-0KA30 is a 1-pole miniature circuit breaker with an auxiliary contact, designed to protect a single circuit while providing a signaling output for status feedback. With a rated current of 6 A, it is suited to small-load applications where compact protection is required and where the auxiliary contact can be wired to a control circuit to indicate whether the breaker is energized or has tripped. The auxiliary contact is integrated into the device, enabling signaling without a separate switch module and allowing signaling to be used in interlock or monitoring logic in automation or control panels. This Siemens part, model 5SN1706-0KA30, combines a single-pole protective function with a built-in signaling contact, providing a basic solution for installations that require overload protection plus status feedback. As part of Siemens' lineup of protective devices for low-voltage systems, the 5SN1706-0KA30 is identified by its 1P configuration, 6 A rating, and inclusion of an auxiliary contact.
