It runs on 48 V AC or 48–72 V DC control voltage and triggers at 14.2 x Ir for fast fault clearing. Mounts plug-in (front face) with IP20 on the front panel, sized 2.4 x 1.8 x 2.6 in. Manual reset style — you trip it, you walk over and push the button. Rated for AC-44, AC-43, AC-41 utilization categories. Thermal overload class 10, immunity to voltage dips 70% / 500 ms, resistance to fast transients 4 kV, control circuit draws 280 mA peak, 45 mA sealed.","metaTitle":"LUCB32ES TeSys Ultra Control Unit, 48 V AC/DC","metaDescription":"TeSys Ultra LUCB32ES advanced motor protection control unit, 48 V AC/DC.
