The 100-D115ZA22L contactor is a non-reversing DC contactor that has been included in the Allen-Bradley Bulletin 100-D series. This contactor and the whole Bulletin 100-D series are manufactured by Allen-Bradley/Rockwell Automation and it is primarily intended for use in the automation industry, especially in applications with motors that require high DC voltages. This contactor comes with 3 main contact poles embedded in it that have conventional coils. These coils are made with a gold-plated material. This contactor also has 2 N.O. and 2 N.C. auxiliary contacts that perform the mirror contact function when necessary. The Allen-Bradley/Rockwell Automation 100-D115ZA22L non-reversing DC contactor has current ratings of 115 Amps and 250 Amps at 60 degrees Celsius and 40 degrees Celsius, respectively. If the operating temperature is between 60 and 70 degrees Celsius, the current rating must be derated by at least 15 percent so that the contactor can continue with regular operations without risking damage.

The Allen-Bradley/Rockwell Automation 100-D115ZA22L Bulletin 100-D non-reversing DC contactor operates with a DC voltage rating of up to 500 Volts DC. This contactor can be installed on a panel for maximum stability during operation. It comes with a compact design that makes its installation process easy. After the installation is complete, it is important to ensure that the pickup winding is interconnected properly with one of the N.C. or normally closed auxiliary contacts. The Allen-Bradley/Rockwell Automation 100-D115ZA22L non-reversing DC contactor operates with a non-reversing mechanism and thus, it must be paired only with motors and machinery that operate in the same way. For reversing types of equipment, a different type of contactor must be selected from the same catalog. This non-reversing contactor can be used with different sets of accessories for custom applications.
