Part Identification and Compliance
The control circuit operates on 220-230 V AC at 50/60 Hz, with a silent AC coil drawing 3 VA inrush at 20 °C. The contactor is fully compliant with EN/IEC 60947-4-1, GB/T 14048.4, UL 60947-4-1, CSA C22.2 No 60947-4-1, and JIS C8201-4-1, making it suitable for tender submissions requiring multi-standard certification.
Rated for AC-1 duty, this contactor carries a thermal current (Ith) of 20 A at 50 Hz, with an average power circuit impedance of 3 mOhm per pole. The electrical durability is specified at 0.3 million cycles at 20 A AC-1 up to 440 V, while mechanical durability reaches 10 million cycles. For safety circuit integration, the B10d value is 1,369,863 cycles under nominal load per EN/ISO 13849-1, and 20,000,000 cycles under mechanical load only. The rated breaking capacity is 110 A at 440 V, 80 A at 500 V, and 70 A at 660-690 V per IEC 60947. The rated making capacity is 144 A AC for the power circuit. These figures confirm the contactor is sized for moderate resistive loads in control panels, not for motor starting (which would require AC-3 rating).
Connections use Faston terminals: two cables for 2.8 mm busbar cross-section, or one cable for 6.35 mm busbar. The associated fuse rating is 25 A gG or 25 A aM for the power circuit. Heat dissipation is 3 W, which should be considered in panel thermal calculations. The maximum operating rate is 3600 cycles per hour.
