Note: When using the Catalogue Numbering System for Eaton’s Cutler-Hammer IT. Electro-Mechanical products, care should be exercised to
assure that the Catalogue Number for the Overload Relay aligns with the IT. Contact Block selected for type, frame size and ampacity, if pur-
chased as separate components. Example: Select an E05N_XR_3A IT. Overload Relay for an IEC non-reversing application or an E06N_XR_3A
for an IEC reversing application.

Examples:

E02NCXCXNN — FVNR Coil Controller, 54 mm
E04NB18X3N — Contact Block, 45 mm, 18 Amps
E05NCXRL3A — Solid-State Non-reversing Overload Relay, 16 – 50 Amps
E101B32J3A — FVNR B-Frame Starter, 32 Amps, with Solid-State Overload, 10 – 32 Amps
E111F25X3N — FVNR F-Frame Contactor, 250 Amps
E501D10K3A — FVR D-Frame Starter, 100 Amps, with Solid-State Overload, 14 – 45 Amps
E511B18X3N — FVR B-Frame Contactor, 18 Amps

IEC Full Voltage Non-reversing
Contactor, C-Frame
Cat. No. E111C50X3N

Product Description

The Cutler-Hammer® Intelligent
Technologies (IT.) Electro-Mechanical
Contactor from Eaton’s electrical
business consists of an IT. Electro-
Mechanical Contact Block and IT.
Electro-Mechanical Coil Controller
as a Full Voltage Non-reversing
(FVNR) or Full Voltage Reversing
(FVR) device. B-Frame (45 mm) to
E-Frame (105 mm) Contact Blocks
combined with Coil Controllers
(factory or field assembled) are
stand-alone Contactors. Only the
A-Frame (27 mm) and F-Frame
(140 mm) Contactors have internal
factory assembled coil controllers.

Also available are the
Combination Motor Controllers which
combine a Manual Motor Protector,
Wiring Connector Link and
tor.

Application Description

When selecting an IEC Contactor, the
user must consider the specific load,
utilization category and required elec­trical life. Actual application life July
vary depending on environmental
conditions and duty cycle.
