MS&MO series manual motor starters

Manual motor starters are electromechanical protection devices for the main circuit. They are used mainly to switch motors manually ON/OFF and to provide fuse less protection against short-circuit, overload and phase failures. Fuse less protection saves costs, space and ensures a quick reaction under short-circuit condition by switching off the motor within milliseconds.

Main benefits:

Harmonized main accessory range (auxiliary contacts, signal contacts, shunt trips and undervoltage releases) for MS1xx and MO1xx family

Compact design

Efficient planning and installation perfectly matching the ABB contactor family

Simple connecting links ensure electrical and mechanical connection to build direct-on-line starters

Less machine downtime by protecting motors and reduced trouble shooting and reduced maintenance expenditures by protecting motors

ABB’s Push-in Spring terminals offer unique, fast , easy and reliable connections

Main features:

Manual control / short-circuit current and overload protection

Adjustable current setting for overload protection and magnetic trip indication

Disconnection function

Temperature compensation

Remote control via undervoltage release or shunt trip

Short-circuit service breaking capacity Ics up to 100 kA.
