Note: When using the Catalog Numbering System for Eaton’s Cutler-Hammer IT. Electro-Mechanical products, care should be exercised to assure that the Catalog Number for the Overload Relay aligns with the IT. Contact Block selected for type, frame size and ampacity, if purchased as separate components.

Examples:

N101BS0J3A — Full Voltage Non-reversing, Size 0 Starter with a 10 – 32 amp overload range

N111FS5X3N — Full Voltage Non-reversing, Size 5 Contactor

N501DS2K3A — Full Voltage Reversing Starter with a 14 – 45 amp overload range

N02NCXCXNN — Coil Controller 54 mm

N04NBSAX3N — Contact Block Size 00
