Its conventional free-air thermal current (Ith) is 20 A at 50 °C for the power circuit, and the rated operational current (Ie) is 20 A at 690 V AC, 50/60 Hz. That AC-1 rating means it handles resistive loads like heaters or lighting banks at full rated current without derating for motor inrush; for motor duty (AC-3) you would need a different rating. The coil is 60 V DC, with an operating range of 0.8 to 1.15 times the control voltage and a drop-out band of 0.1 to 0.75 Uc below 50 °C. Inrush power at 20 °C is 3 W; hold-in power is also 3 W — a continuous-duty coil, not a power-saver design.
Screw-clamp terminals accept a Philips No 2 or flat 6 mm screwdriver at 1.3 N·m tightening torque. The 4-pole, all-NO configuration means it switches four independent resistive circuits simultaneously; no auxiliary contacts are integrated, so add a separate block if you need a feedback signal.
