Rated operational current is 1 A at 690 V, 50/60 Hz, with a Class 10 trip class — meaning the thermal overload element will trip within 10 seconds at 7.2× rated current, fast enough to protect a small control transformer or a lightly loaded motor branch. The AC-3 rating (1 A at 400 V) confirms it can switch motor loads under starting conditions, but the primary design target here is transformer primary-side protection — the magnetic short-circuit trip clears faults before the transformer winding saturates.
Panel fit and mounting — S00 size, DIN-rail snap-on
Main circuit connections are screw-type terminals top and bottom, accepting 2×(0.75–2.5 mm²) solid/stranded or 2×4 mm², with a tightening torque of 0.8–1.2 N·m.
Lifecycle and sourcing — active production, available to order
RoHS compliance date is May 1, 2012, covering the EU RoHS substance restrictions; the part carries no REACH SVHC exceedance flag in the recorded data.
