Compact multi-function electronic motor starter with integrated motor protection
02 June 2013
Eaton has introduced a multi-functional motor starter with integrated motor protection in a 30mm mounting width for motors with ratings from 0.06 to 3kW.
The new EMS electronic motor starter combines DOL start, reversing start, motor protection and emergency stopping to category 3 (EN 13849-1) in a single switching device. This reduces the wiring requirement compared to conventional switchgear assemblies by up to 60 percent and the proportion of hardware components required by up to as much as 70 percent.
The slim unit optimises the use of space in the control panel, helping to ensure a uniform panel design. The use of tool-less push-in technology also keeps installation requirements to a minimum, whilst the hybrid switching technology increases the lifespan of contacts.
The integrated hybrid switching technology based on wear-free semiconductor technology and a robust relay contact ensure the low-wear switching of the EMS. This relieves the load on the actual relay contact for actuating the motor.
With a life of up to 30 million switch operations, this electronic motor starter offers a considerably longer contact lifespan than conventional switching devices.
All variants of the electronic motor starter come with electronic wide-range overload protection with integrated phase failure detection to IEC60947. This enables the switching device to cover the 0.18 to 6.5A (AC-53a) and 9A (AC-51) current ranges with only two devices, thus simplifying device selection and spare parts management.
