The 100-E190KN11 3-Pole AC/DC Operated Contactor is an IEC 100 Contactors series contactor from the Allen-Bradley Bulletin 100E product line of large frame contactors. The 100-E190KN11 Contactor offers bolt-in terminal connections to the main circuit current. All the other contacts on the 100-E190KN11 Contactor circuits have bolt-in type terminals for making fast and simplified field-through wiring connections. The 100-E190KN11 Contactor is designed for 3-phase connections, and it comes with 3 main contacts that are all normally open for direct 3-phase wiring. The 100-E190KN11 Contactor supports direct wiring to 3-phase power supplies, and when it is used with direct-on-line starters, it can be used to wire 3-phase AC motors to the direct power supply. The 100-E190KN11 Contactor also has 2 factory-fitted side-mounted auxiliary contacts (1 normally open and 1 normally closed) with bolt-in terminals.

The Allen-Bradley 100-E190KN11 Contactor has a universal electronic control coil that accepts AC/DC actuating voltage. This AC/DC coil helps to expand the application options of the 100-E190KN11 Contactor and to make the device selection process easier. The 100-E190KN11 Contactor’s coil has a rated control voltage rating of 250 Volts DC to 500 Volts DC or 250 Volts AC to 500 Volts AC (at 50 Hertz). The coil has Class F insulation that offers thermal stability at full loads. The 100-E190KN11 Contactor has a rated operating current of 190 Amps for AC-3 motors at 400 Volts AC and 275 Amps at 400 Volts AC for AC-1 motors. The 100-E190KN11 Contactor’s main circuit is designed to accept AC or DC inputs. It has a rated operating voltage range of 24 to 440 Volts DC or 115 to 575 Volts AC. It also has a maximum switching power rating of 90 Kilowatts with AC-3 motors at 415 Volts AC.
