The \"Q\" in the part number indicates the 4-pole \"auxiliary\" configuration: 4 main poles that are all normally-open (4a), so the SD-Q12 is typically used as a control relay inside motor-starter assemblies, lighting panels, HVAC control cabinets, and PLC I\/O interposing relays where a higher inrush than the PLC output can handle needs to be switched by a coil-driven contact block.\n\u003c\/p\u003e\n\n\u003cp style=\"color:#333333; font-family:Arial, Helvetica, sans-serif; font-size:15px; line-height:24px; margin:0 0 16px 0;\"\u003e\n  At \u003cstrong\u003e\u003ca href=\"https:\/\/koeed.com\" style=\"color:#0056B3; text-decoration:none;\"\u003ekoeed.com\u003c\/a\u003e\u003c\/strong\u003e we list the SD-Q12 as a \u003cstrong\u003econtrol-cabinet contactor \/ relay\u003c\/strong\u003e.
