11B145SL00380 - 3P CONTACTOR 380/415V W/O LATCH

Why Choose the 11B145SL00380?

The Lovato B145 three‑pole contactor is engineered for dependable motor and power switching, delivering an IEC AC3 operating current of 150 A. Its universal AC/DC coil operates at 380–415 V, simplifying control integration across systems. With a rated insulation voltage of 1000 V and 8 kV impulse withstand, this contactor provides robust dielectric performance for demanding industrial environments.

Built for longevity and reliability, the B145 offers 10,000,000 mechanical cycles and a wide operating temperature from −50 to 70 °C. Screw mounting and 18 Nm terminal tightening torque support secure installation, while Ith is 250 A. Predisposed for mechanical latch (G495), it suits hold‑in requirements. Conforms to IEC/EN 60947-1/-4-1 and UL/CSA equivalents for assured compliance up to 3000 m, pollution degree 3.
