11B145SL00220 - 3P CONTACTOR 220/240V W/O LATCH

Why Choose the 11B145SL00220?

The Lovato B145 three-pole contactor (SKU 11B145SL00220) provides dependable AC-3 motor switching at 150 A via a 220-240 V AC/DC coil. With secure screw mounting for straightforward panel installation, it is predisposed for the G495 mechanical latch where maintained contact is needed. This contactor supports efficient control of heavy loads while offering coil supply flexibility across both AC and DC control circuits.

Engineered for resilience, the B145 features Ui 1000 V insulation and 8 kV impulse withstand, with Ith 250 A for thermal endurance. A mechanical life of 10,000,000 cycles supports long service in harsh environments from -50 to +70 °C and up to 3000 m altitude (pollution degree 3). Conformity with IEC/EN 60947-1/-4-1 and UL/CSA 60947 standards simplifies specification across global projects.
