Multi-role motor starter cuts wiring by up to 60%
Published:  11 June, 2013

A new multifunctional motor starter from Eaton combines four functions – direct-on-line starting, reversing starting, motor protection and emergency stopping. The EMS electronic starter is said to cut wiring requirements compared to conventional switchgear assemblies by up to 60% and the number of hardware components by up to 70%.

The 30mm-wide starter also saves cabinet space, while its use of tool-less push-in wiring for the main and control terminals cuts wiring times by up to 60% compared to screw terminals.

The starters use a hybrid switching technology based on wear-free semiconductors and robust relay contacts, relieving the load on the motor-actuating relay contacts. Eaton claims the device will achieve up to 30 million switching operations and offer a lifespan up to ten times longer than purely mechanical components.

Electronic overload protection with integrated phase failure detection allows the devices to cover 0.18–6.5A and 9A current ranges with just two versions. Overload protection is provided to Class 10 and 10A tripping classes. Users can set the motor current on the starter.
