Power circuit ratings and duty
The LC1E40008M5WB is a 4-pole contactor from the Easy TeSys Control range, rated 60 A in AC-1 utilisation category at ≤440 V — meaning it is specified for resistive loads such as heaters or lighting banks, not motor starting. The power circuit carries a rated insulation voltage of 690 V conforming to IEC 60947-4-1, with a rated breaking capacity of 320 A at 440 V and a making capacity of 400 A at 440 V AC. Average impedance per pole is 1.5 mOhm at 50 Hz, and power dissipation per pole runs 5.4 W under AC-1 duty. For fault coordination, the associated fuse is 80 A gG at ≤690 V, coordination type 1.
Control circuit and coil
The control circuit is AC at 50 Hz wide range, with a nominal voltage of 220 V AC 50 Hz. Inrush power is 160 VA at 50 Hz, cos φ 0.75, at 20 °C. Drop-out occurs at 0.3 to 0.6 Uc, operational range is 0.7 to 1.25 Uc across -5 to 55 °C. Operating time is 20 to 26 ms on closing, 8 to 12 ms on opening. Heat dissipation for the control circuit is 6 to 10 W.
Mechanical and environmental
Mounts on plate or DIN rail. Dimensions: 85 mm wide, 127 mm high, 110 mm deep. IP2X finger protection conforming to IEC 60529.
