Motor protection circuit breaker, size S00, adjustable 0.45–0.63 A
The adjustable overload release covers a 0.45 to 0.63 A range, letting you dial in the exact motor FLA without swapping the breaker — per the datasheet, the current-dependent overload release is set via a rotary dial on the front face. The magnetic short-circuit trip (N-release) is fixed at 8.2 A, which clears a locked-rotor condition before the thermal element can overheat.
Screw-type terminals on top and bottom accept solid or stranded copper up to 2.5 mm² (2× per terminal), with a tightening torque of 0.8 to 1.2 N·m using a Pozidriv size 2 bit. The S00 size allows direct mechanical interlocking with SIRIUS contactors of the same frame — no adapter bracket needed for a reversing or star-delta starter assembly. Side clearance of 9 mm to adjacent devices is sufficient for heat dissipation; the breaker dissipates 5.5 W at rated current in hot operating state, or 1.8 W per pole.
