The 24 V DC coil holds at nominal and drops out below the typical threshold for this class — verify your control supply stays above 18 V under load. The auxiliary contact rating of 10 A at 24 V is for resistive loads; inductive loads require derating per the switching frequency limits: 1 000 cycles/hour for AC-1, AC-2, and AC-3 duty, dropping to 300 cycles/hour for AC-4 (plugging and inching). The S0 frame size limits main contact current handling compared to larger S2 or S3 frames — this is sized for smaller motor loads up to roughly 5.5 kW at 400 V AC-3, though the exact motor rating depends on the specific utilization category.
Wire range accepts 1 to 10 mm² solid or stranded for main power connections; auxiliary terminals accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²).
