It supplies the necessary magnetic force to pull in and hold the main contacts when your control circuit is at 24 VDC. ## Installing or swapping This coil wires straight onto the D-N300 contactor base — same terminal layout, same mounting slots. The 24 VDC rating matches a standard panel control transformer or PLC output; verify polarity on DC coils if your contactor has freewheeling diode suppression, otherwise reverse-polarity protection is internal.","metaTitle":"SD-N300 DC24V Replacement Coil for D-N300 Contactor, 24 VDC","metaDescription":"SD-N300 DC24V is a current-production replacement coil for D-N300 magnetic contactors. Rated 24 VDC, it mounts directly without panel rework.
