Motor Starter · 5 hp 230V 3-phase · non-combination non-reversing · Eaton ECX09F5BAA

What this product is for

The Eaton ECX09F5BAA is an enclosed IEC motor starter for across-the-line starting of 230V 3-phase motors up to 5 hp. It is a non-combination, non-reversing starter used where the branch circuit protection is provided separately.

Use for

Use for pumps, fans, conveyors, compressors, and other industrial or light commercial equipment requiring a 230V 3-phase starter with a 240V control coil. It is commonly used where a compact enclosed starter is preferred for washdown, damp, or corrosive locations.

Avoid for

Avoid for reversing applications, combination starter applications that require an integral disconnect or short-circuit protective device, or installations where the overload range has not been matched to the motor nameplate FLA.

Best for

Best for electricians and maintenance teams needing an enclosed XT series starter with Type 4X/IP66 protection and a straightforward non-reversing configuration.

Installed in

Typically installed in industrial plants, commercial mechanical rooms, agricultural buildings, and outdoor or washdown-adjacent areas. The enclosure family is listed by Eaton as non-metallic and compact, with common sizes including approximately 6.3 x 3.9 x 5.7 in (160 x 100 x 145 mm) for models in this range.

Why this product exists

This starter provides enclosed motor control where users need contactor and overload protection in one compact assembly, but do not need a built-in disconnect. It helps simplify motor control selection for common 3-phase loads while keeping enclosure protection suitable for demanding environments.

Compared with similar products

Compared with an open starter, this enclosed version is better suited to wet or dirty locations. Compared with a combination starter, it does not include the integral disconnect or branch protection device, so upstream protection must be provided separately. Typical motor starter selection should also confirm motor FLA, control voltage, enclosure type, and whether reversing is required.

Rule of thumb: motor starters are commonly selected by matching horsepower, supply voltage, phase, and motor full-load amperage. Actual suitability depends on the motor nameplate, duty cycle, ambient conditions, and local electrical code.
