The Allen-Bradley 100-D300EZA11 DC-operated contactor is a 3-phase contactor with an electronic coil. It belongs to the Bulletin 100-D contactor family. The Bulletin 100-D contactor family is a series of cost-effective switching solutions to applications that require output power ratings of up to 500 kilowatts. These contactors also feature a rugged and compact design that help to reduce installation costs and minimize panel space requirements. The 100-D300EZA11 contactor features an IP 20 ingress protection rating. This touch-free enclosure is resistant to dust and prevents the users from touching or otherwise accessing the internal components. The 100-D300EZA11 contactor has 2 side-mounted auxiliary contacts with a snap-in design. The auxiliary contacts are 1 normally open contact and 1 normally closed contact, and they help simplify the feed through wiring. 

The Allen-Bradley 100-D300EZA11 Bulletin 100-D contactor supports a wide range of Bulletin 100-D accessories and renewal parts. Additional auxiliary contacts, terminal lugs, control circuit terminals, mounting plates, terminal covers, and terminal shields can be ordered to enhance and refine the contactor’s functionalities. The 100-D300EZA11 contactor has 3 normally open contacts as the main contactor contacts. It has flat-type terminals that support bolt-in connections to the main power supply. The 100-D300EZA11 contactor has a rated breaking current of 300 Amps and a maximum switching power rating of 160 kilowatts at 415 Volts AC. The 100-D300EZA11 contactor features built-in surge suppression for protection against high voltage spikes. It has an impulse withstand rating of 12 kilovolts and an isolation rating of 1000 Volts per the IEC standards. The 100-D300EZA11 contactor has Class B insulation for high electrical and thermal protection for its coil.
