The control circuit is rated 220...240 V AC at 60 Hz, with a drop-out threshold of 0.2...0.75 Uc and an operating range of 0.85...1.1 Uc at 50 °C. Rated for utilisation categories AC-7A and AC-7B per IEC 61095 and IEC 60947-5, this contactor handles the inrush and breaking demands of small motors, resistive heating banks, and lighting circuits. The power circuit carries a rated breaking and making capacity of 40 A at 400 V AC. Average impedance is 2.5 mOhm at Ith 16 A, 50 Hz, with heat dissipation of 1.6 W at 50/60 Hz and 0.65 W per pole.
The screw-clamp terminals accept up to 6 mm² solid or flexible cable on the power circuit and 2.5 mm² on the control circuit, all torqued to 0.8 N·m. IP20 protection (VDE 0106) out of the enclosure; IP40 when enclosed. Operating altitude up to 3000 m. Mechanical durability is rated at 1,000,000 cycles, with electrical durability of 100,000 cycles under both AC-7A and AC-7B duty at the maximum operating rate of 300 cycles per hour at 50 °C. The contactor withstands shocks of 10 Gn (open) and 15 Gn (closed), and vibrations of 2 Gn (open) and 3 Gn (closed) across 5...300 Hz.
