11B115L00380110 - 3P CONTACTOR 380/415V C/W LATCH 110VAC

Why Choose the 11B115L00380110?

Lovato’s B115 three-pole contactor delivers dependable switching for AC-3 duty at 110 A. An AC/DC coil rated 380…415 V is supplied, with a factory-fitted mechanical latch (G495) operating at 110…125 V AC. Designed for screw mounting, it offers strong electrical performance with a rated insulation voltage Ui of 1000 V and an impulse withstand voltage Uimp of 8 kV.

It is built for longevity, with mechanical life tested to 10,000,000 cycles and an Ith of 160 A. Reliable across harsh conditions, it operates from −50 to 70 °C, stores from −60 to 80 °C, functions up to 3000 m altitude, and suits pollution degree 3 environments. Conforms to IEC/EN, UL, and CSA standards, with sustainability certification.
