BF330T4E110 LOVATO MAXI 4P CONTACTOR 500A AC1 60-130VAC/DC

Why Choose the BF330T4E110?

Engineered for demanding switching duties, the Lovato BF330T4E110 four-pole contactor combines high current capacity with a versatile AC/DC coil. Rated Ith (AC1) at 500 A and delivering AC3 performance of 330 A/160 kW at 400 V, it suits heavy-duty motors and resistive loads. The 60…130 V coil range simplifies control design, while screw mounting ensures a secure, serviceable installation for panels and machinery.

Built for reliability, the BF330 platform offers Ui 1000 V and Uimp 8 kV insulation strength, plus a mechanical life of 5,000,000 cycles. It operates from -40 to 70 °C and stores from -50 to 80 °C up to 3000 m, pollution degree 3. Conformity to IEC/EN/BS 60947 and UL/CSA standards supports compliance across industrial automation and power distribution applications.
