Description:

The Schneider Electric EK300-1 Electrical Interlock (often listed as EK3001) is a 30 A SPDT interlock kit for Square D heavy‑duty safety switches, delivering one normally open and one normally closed contact. It is designed to interlock a companion disconnect or feed a control circuit, enabling safe sequencing in safety-switching configurations. Compatible with Square D Series E1–E2 heavy‑duty disconnect switches and commonly used with Class 3110 safety switches, the EK300-1 attaches to the disconnect to provide electrical interlock signaling without replacing the main operating mechanism. The -1 suffix denotes a single interlock with 1 NO and 1 NC contact, offering simple integration into control circuits and interlock logic.
