Product Description
The Cutler-Hammer
®
Intelligent
Technologies (IT.) Electro-Mechanical
Starter from Eaton’s electrical business
consists of an IT. Electro-Mechanical
Contact Block or Contactor and IT.
Electro-Mechanical Solid-State
Overload Relay as a Full Voltage
Non-reversing (FVNR) or Full Voltage
Reversing (FVR) device. Size 00 to Size 5
Starters are factory or field assembled.
Features
■ 24V DC control power — safe, reliable
global standard
