More flexibility with less components

The easyE4 base devices and input/output expansion modules are available with DC,

AC and UC (universal) voltage, which makes the devices ideal for use in machine

building or building applications. By means of up to 11 expansion modules, the base

devices can be expanded to max. 188 inputs/outputs. All the expansions can be mixed

and combined as required. Thanks to the clever plug-in technology, the expansion

modules can be quickly connected or replaced.

The easyE4 control relay from Eaton’s Moeller series is ideally suited for

implementing the control and regulation of small to medium complex 

applications efficiently and flexibly. It offers a wide range of custom and

simple visualization options: whether on mobile devices thanks to the web

server including the integrated web-editor or with the easyE Remote Touch Displays.

The device can also be connected directly to Amazon Web Services (AWS).

The easyE4 series offers a wide range of communication options via the integrated

Ethernet interface featuring the functions of a mini-PLC for machine and system control.

With the integrated Modbus TCP client and server functionality, components of different

levels can be integrated. The communication modules for Modbus RTU and SmartWire-DT

make the easyE4 to a smart relay enabling the monitoring machines and systems.

Many other functions make the easyE4 a powerful micro controller that can also be

integrated into IoT system architectures.

Think differently about effortless control

The easyE4 PLC has 12 I/O and can be expanded to a network of up to 188 I/O points,

providing the ideal solution for lighting, energy management, industrial control, irrigation,

pump control, HVAC and home automation. In whatever your application, the compact and

flexible easyE4 enables control systems that are efficient and effortless to implement.

After the easyE4 is installed, changes are easily accomplished through front panel

programming, which eliminates the need to change wiring and minimizes downtime.

Gain effortless control with the easyE4.

Look to Eaton’s Cooper PowerE series 600 A 35 kV class DirectConnect

elbow arrester to offer wind farm customers significant cost savings and

ease of installation.

This new deadbreak design replaces three components:

bushing extender, loadbreak reducing tap plug and the traditional 200 A

elbow arrester. The DirectConnect elbow arrester is available in two design

options: VariGAP and M.O.V.E. Eaton values your trust in our experience to

engineer products that save you money.

Reliability, cost savings and ease of installation

Eaton is now combining their 40+ year track record in separable connectors

and 27 years in underground arresters to introduce the 600 A DirectConnect

elbow arrester.

Eaton offers a cost-effective design with a shorter stacking height.

With this design, you no longer have to worry about clutter or not being able to

fit your cable accessories into smaller enclosures. The DirectConnect elbow arrester

replaces three components with one and is over 50% smaller in size than the

traditional offering, cutting installation time by 80%.

Not only does this design save you money on direct material costs, but it also

reduces overall labor expenses.

The DirectConnect elbow arrester utilizes the design expertise and manufacturing

know-how that contractors, developers and owners alike have come to rely on from

Eaton. Specific for 35 kV wind farm applications, the VariGAP design option provides

enhanced temporary overvoltage (TOV) characteristics for superior MCOV performance

over time. The VariGAP design is available in 27 kV and the standard M.O.V.E. design

is available in 27 kV and 30 kV ratings. Installation is easy. Simply thread the adapter

into a standard 600 A bushing and install the DirectConnect elbow arrester onto the

bushing. The probe inside the arrester latches into the adapter.

Design features and benefits

• Replace three components with one DirectConnect elbow arrester

• Save material costs with the DirectConnect arrester over bushing extender,

loadbreak reducing tap plug, and 200 A elbow arrester

• Reduce stocking requirements

• Shorter stacking height

• Decrease stacking height more than 50%

• Fits into smaller enclosures

• Reduces pulling force due to elimination of cantilever effect

• Easily retrofittable to existing 600 A installations

• Simply replace the bushing extender, loadbreak reducing tap plug and 200 A elbow

arrester with an adapter and a DirectConnect elbow arrester

• TOV performance

• Enhanced temporary overvoltage characteristics

• 36 kV—highest TOV in the industry

• Arresters that will survive higher AC overvoltages, reducing downtime

• Increased system reliability

• EPDM molded rubber deadfront construction

• 40+ years of experience in EPDM rubber cable accessories and 27+ years

of elbow arrester technology

• Eaton is the only separable connector manufacturer that mixes and blends its own

insulation in-house

• Eaton’s chemists maintain control of the formulation at all times

• Ease of installation

• Cuts installation time by 80% versus installing three components

• Visually can verify contact with threads, which reduces chance of cross threading

• No special training required for linemen or contractors

Standard design tests

• IEEE Std 386E separable insulated connector systems

• IEEE Std C62.11 metal oxide surge arresters for AC power circuits
