The 100-E38EQ200 contactor is an Allen-Bradley/Rockwell Automation brand 4-pole direct-on-line contactor that does not come with built-in auxiliary contacts. Its 4 main poles are 2 NC (normally closed) contacts and 2 NO (normally open) contacts. The 100-E38EQ200 direct-on-line 4-pole contactor is part of the Allen-Bradley IEC 100 Contactors series and it supports both AC operation and DC operation. It has been designed to operate efficiently with low levels of power consumption to save energy and to be environmentally friendly. The coil voltage rating of the 100-E38EQ200 direct-on-line 4-pole contactor is 12 to 20 Volts DC. This direct-on-line contactor is frequently used to build custom contactor systems that can meet the needs of different applications. It can be used with optional accessories in some applications.

One of the optional accessories that is available for the Allen-Bradley/Rockwell Automation 100-E38EQ200 4-pole direct-on-line contactor is a paralleling terminal. Paralleling terminals can be used to connect poles in a parallel formation that can allow a greater AC-1 load to pass through the flow path that the parallel poles create than is possible without the terminals. Wye-Delta power wiring kits are also available as optional accessories for the 100-E38EQ200 4-pole direct-on-line contactor. These kits connect the main poles of Delta, Star, and Line contactors in a Star-Delta type of starter. The types of connections that are supported by these kits include line-side phase-to-phase connections, load-side connections in a parallel formation, and star-point line-side connections. If the 100-E38EQ200 4-pole direct-on-line contactor needs auxiliary contacts, an optional front-mounted auxiliary contact block can be installed.
