11B1804SL00220 - 4P CONTACTOR B180.4SL 220/240V

Why Choose the 11B1804SL00220?

Lovato 11B1804SL00220 is a B180 four‑pole contactor designed for demanding AC‑1 switching. With an IEC Ith of 275 A, an AC/DC coil rated 220…240 V, and screw mounting, it integrates easily into industrial control panels. Rated insulation voltage Ui 1000 V and impulse withstand Uimp 8 kV deliver strong dielectric performance. The device is predisposed for a mechanical latch (G495) to enable optional latching functionality when required.

Built for longevity and harsh environments, the contactor offers a mechanical life of 10,000,000 cycles and operates from −50 to +70 °C (storage −60 to +80 °C). It is rated for use up to 3000 m altitude and pollution degree 3. Terminals support a specified tightening torque of 18 Nm. Conforms to IEC/EN 60947-1 and 60947-4-1, with UL and CSA approvals, and carries a Sustainability certification.
