11B25040060 - 4P CONTACTOR B250.4.00 60V

Why Choose the 11B25040060?

Engineered for demanding power switching, the Lovato B250 four‑pole contactor (SKU 11B25040060) delivers a robust 350 A Ith (AC‑1) with a 60 V AC/DC coil. With a rated insulation voltage Ui of 1000 V and 8 kV impulse withstand, it provides dependable performance in industrial control systems. Screw mounting simplifies panel integration, and compliance with IEC/EN 60947‑1 and 60947‑4‑1 supports UK specification needs.

Built for endurance, the B250 achieves 10,000,000 mechanical cycles and operates from -50 to 70 °C, with storage from -60 to 80 °C. Suitable for installations up to 3000 m altitude and pollution degree 3, it secures connections with 35 Nm terminal tightening torque. At 1080 g, the unit integrates cleanly, and UL and CSA standards complement IEC/EN conformity for international projects.
