Rated conventional free-air thermal current is 10 A at 50 °C, with a rated insulation voltage of 690 V conforming to IEC 60947-5-1 and UL 60947-5-1. The 35 mm depth and 38 mm width keep it compact on the front of the contactor, and the spring terminals accept 0.75 to 1.5 mm² flexible or rigid wire without ferrules.
The 690 V insulation voltage (Ui) covers most 400 VAC and 480 VAC control circuits, and the 110 A making capacity (at 10 MOhm) handles the inrush of a contactor coil or small solenoid without welding the contacts.
