The 100-E146KN11 IEC Contactor from Allen-Bradley is a 3-pole AC/DC contactor that is designed for large-frame industrial applications. The 100-E146KN11 Contactor features screw-type wiring terminals for connections to the main current circuit. These contact terminals provide a fast and simplified wiring process for making connections to the main power source. The 100-E146KN11 Contactor has 1 Normally Open (NO) and 1 Normally Closed (NC) contact as built-in auxiliary contacts. Additional auxiliary contacts (up to 4 additional contacts) can be ordered separately to meet application demands. The 100-E146KN11 Contactor has 3 main contacts (3 poles) that are all Normally Open (NO). It supports a direct-on-line connection, which connects 3-phase AC motors directly to a 3-phase power supply. The 100-E146KN11 Contactor has a universal AC/DC coil that helps to streamline device selection. 

The 100-E146KN11 Contactor offers a wider coil range and a lower coil consumption power rating than many other contactors do. The electronic AC/DC coil has an actuating voltage range of 250 to 500 Volts AC (with 50 to 60 Hertz frequency) or 250 to 500 Volts DC. The AC/DC coil comes with IEC rated “Class F” insulation for providing thermal stability even at full loads. The 100-E146KN11 Contactor has a rated operating current of 146 Amps with AC-3 motors at 400 Volts AC and 50 Hertz input and 225 Amps with AC-1 motors at 690 Volt AC (60 Hertz) input. The 100-E146KN11 Contactor supports a direct connection to either an AC or DC power supply. It has a rated operating voltage range of 115 to 575 Volts AC or 24 to 440 Volts DC. The 100-E146KN11 Contactor has an isolation voltage rating of 690 Volts and a maximum impulse withstand rating of 8000 Volts. The 100-E146KN11 Contactor has an IP2X protection class and it has a wider operating temperature range.
