11B145L00380380 - 3P CONTACTOR 380/415V C/W LATCH 380VAC

Why Choose the 11B145L00380380?

Lovato B145 three-pole contactor (SKU 11B145L00380380) delivers reliable AC‑3 motor duty at 150 A with an AC/DC coil rated 380–415 V. Supplied with a pre‑fitted mechanical latch (G495), it supports latched operation when required. Robust electrical ratings include Ui 1000 V and Uimp 8 kV, while secure screw mounting simplifies panel integration in industrial control applications compliant with IEC/EN 60947-1 and 60947-4-1.

Built for endurance, this contactor offers an Ith of 250 A and an exceptional mechanical life of 10,000,000 cycles. It operates from −50 to 70°C, stores from −60 to 80°C, and is suitable up to 3000 m altitude in pollution degree 3 environments. Terminals accept 18 Nm tightening torque, and the unit weighs approximately 6250 g, with additional UL and CSA conformity for global panels.
