Product Description
The Allen-Bradley 100-E190KN11 is a 3-pole AC/DC operated contactor from the IEC 100 Contactors series, part of the Bulletin 100E large frame contactor line. It features bolt-in terminals for simplified wiring of both main and auxiliary circuits (one normally open, one normally closed). Designed for 3-phase connections with three normally open main contacts, it supports direct wiring to 3-phase power supplies and AC motors via direct-on-line starters. Its universal AC/DC electronic control coil, rated for 250-500V DC or 250-500V AC (50 Hz) with Class F insulation, simplifies selection and expands application options. The contactor has a rated operating current of 190A (AC-3, 400V AC) and 275A (AC-1, 400V AC), with a main circuit voltage range of 24-440V DC or 115-575V AC and a maximum switching power of 90kW (AC-3, 415V AC).
Is Your Device Showing These Signs?
The Allen Bradley 100-E190KN11 is frequently repaired for coil failures, indicated by open circuits or short circuits, resulting in contactor malfunction. Technicians address contact erosion on the main contacts, which causes high resistance and overheating. Overload relay tripping issues are resolved through calibration adjustments or replacement of faulty bimetallic strips. We also fix mechanical wear in the armature assembly, preventing proper contact closure and causing operational failures. Replacement of worn or damaged auxiliary contacts is a common repair to ensure accurate signaling and control circuit functionality.

Our Repair Process for the
100-E190KN11
Our repair process for the Allen Bradley 100-E190KN11 begins with a thorough inspection to diagnose coil failures, contact erosion, overload relay issues, armature assembly wear, and auxiliary contact damage. Coil failures, identified by open or short circuits, require coil replacement. Contact erosion on main contacts is addressed through resurfacing or replacement to eliminate high resistance and overheating. Overload relay tripping problems are resolved by calibrating the unit or replacing defective bimetallic strips. Mechanical wear in the armature assembly is corrected by replacing worn components to restore proper contact closure. Finally, worn or damaged auxiliary contacts are replaced to guarantee accurate signaling and control circuit functionality.
