11B145L00220C110 - 3P CONTACTOR 220/240V C/W LATCH 110VDC

Why Choose the 11B145L00220C110?

Lovato 11B145L00220C110 is a B145 three-pole contactor engineered for heavy-duty switching with an AC-3 operating current of 150 A. It features an AC/DC coil rated 220-240 V and is factory fitted with the G495 mechanical latch (latch voltage 110-125 V DC). Screw mounting simplifies secure installation, while robust construction supports demanding industrial panels and motor control tasks where reliable, repeatable performance is essential.

Designed to IEC/EN 60947 and UL/CSA requirements, this contactor offers Ui 1000 V, Uimp 8 kV and Ith 250 A for safety margins in harsh environments. It delivers up to 10,000,000 mechanical cycles and operates from -50 to +70 °C at altitudes up to 3000 m, pollution degree 3. Terminal tightening torque is 18 Nm and unit weight is approximately 6070 g.
