Motor protection circuit breaker, size S00, CLASS 10, 2 A
The adjustable overload release covers 1.4 to 2 A, letting you fine-tune the protection to the motor's full-load current without swapping the breaker. The magnetic short-circuit release is fixed at 26 A, providing instantaneous trip for fault currents above that threshold. The size S00 footprint — 45 mm wide — fits standard motor starter combinations alongside SIRIUS contactors of the same frame size.
Integrated auxiliary switch and panel integration
This variant includes a factory-fitted transverse auxiliary switch with one normally open and one normally closed contact. The auxiliary contacts share the same screw-terminal block and are rated for control-circuit switching — useful for signaling the breaker state to a PLC or for electrical interlocking in a starter combination. In a densely populated panel, that heat must be considered for enclosure ventilation and derating of adjacent devices.
