51ADX0085B - SOFT STARTER ADX0085B

Why Choose the 51ADX0085B?

Designed for severe duty starts, the Lovato 51ADX0085B soft starter delivers advanced, three phase control with an integrated by‑pass contactor and 85 A rated starter current. Operating across 208…500VAC, it supports motors up to 22 kW at 230 VAC, 45 kW at 400 VAC and 55 kW at 500 VAC, helping reduce mechanical stress while managing starting current to 5•Ie.

Comprehensive functions include motor current thermal protection, current‑limit starting, torque control, kick start and dynamic braking, plus PTC input, event log and RS232 for setup or diagnostics. Built to IEC/EN 60947‑1 and 60947‑4‑2 with IP20 protection and pollution degree 3, it tolerates storage from −30 to +70 °C, ensuring robust performance in control panels across common supply ranges 208…240VAC.
