11B2504L00220220 - 4P CONTACTOR 220/240V C/W LATCH 220VAC

Why Choose the 11B2504L00220220?

Engineered for demanding AC-1 duties, the Lovato B250 four-pole contactor delivers 350 A Ith performance with a universal 220–240 VAC/DC coil. Supplied pre-fitted with the G495 mechanical latch, it enables reliable maintained contact states when required. Robust insulation (Ui 1000 V) and 8 kV impulse withstand, plus pollution degree 3 design, make it a dependable choice for industrial switching and isolation across control and distribution applications.

Built to IEC/EN 60947-1 and 60947-4-1, the B250 features screw mounting and 35 Nm terminal tightening for secure connections. With a mechanical life of 10,000,000 cycles and operating temperature from −50 to +70 °C (storage −60 to +80 °C), it suits harsh sites up to 3,000 m altitude. Weighing 1,140 g and backed by sustainability certification, it supports reliable, long-term panel performance.
