The 3RH2431-1BG40: This voltage-dependent current rating is typical for DC switching where arc extinction governs the limit. The auxiliary contactor is designed for signal-level and control-circuit switching, not motor-load breaking — the instantaneous contacts handle 10,000 switching cycles per hour at AC and a 7–13 ms arcing time at DC.
Mounting flexibility and environmental limits
Clearance distances: 10 mm upward, forward, and downward; 6 mm at the sides. Pollution degree 3 means it tolerates conductive pollution in industrial environments — no conformal coating required for typical panel conditions.
RoHS compliance date is 10/01/2009, confirming the part meets EU substance restrictions. The product extension supports auxiliary switch add-ons, and the closing/holding power of the DC magnet coil is 4 W each.
