Product Description
The Allen-Bradley/Rockwell Automation 100-E40KY00 is a robust IEC 100 series contactor, part of the 100-E/104-E product line, certified to CCC, EAC, UL, CSA, KC, RINA, CE, and SUVA standards. It withstands shock and vibration in industrial environments, operating reliably at altitudes up to 3000 meters and temperatures from -40 to 70C. With IP2X protection, it can be stored from -60 to 80C. This AC/DC compatible contactor features isolation voltages of 690V and 400V, an impulse voltage of 6kV, and rated currents of 40A (AC-3) and 70A (AC-1). For AC motor switching, it offers power ratings from 11kW to 22kW and 10HP to 20HP depending on voltage. It has a 48-130V AC/DC coil voltage range at 50-60Hz and operates on a 3-phase power source, but lacks auxiliary contacts.
Is Your Device Showing These Signs?
