Why Choose the 11B500400110?
The Lovato four‑pole contactor (SKU 11B500400110) delivers high‑capacity switching with an IEC Ith (AC1) of 700 A. Its universal AC/DC coil operates on 110…125 V, simplifying spares and panel design. With AC3 performance at 400 V rated 520 A / 290 kW, the B500 series unit is built for demanding power control while maintaining compact, screw‑mounted installation flexibility.
Engineered for reliability, it offers 1000 V Ui and 8 kV impulse withstand, a mechanical life of 5,000,000 cycles, and operation from −50 to +70 °C. Designed for installations up to 3000 m and pollution degree 3, it conforms to IEC/EN 60947-1 and 60947-4-1, with UL and CSA equivalents recognised for global compatibility.
