Application

The manual motor starters protect the load and the installation against short-circuit and overload. They are three pole protection

devices with thermal tripping elements for overload protection and electromagnetic tripping elements for short-circuit protection.

Furthermore, they provide a disconnect function for safely isolation of the installation and the supply and can be used for the

manual switching of loads.

The manual motor starters have a setting scale in amperes, which allows for direct adjustment of the device without any additional

calculation. In compliance with international and national standards, the setting current is the rated current of the motor and not the

tripping current (i.e., no tripping at 1.2 x I; I = setting current).

Manual motor starters are electromechanical devices for motor and circuit

protection. These devices offer local

motor disconnect means, manual ON/

OFF control, and protection against

short circuit, overload, and phase loss

conditions. Manual motor protection

saves cost, panel space, and ensures

fast and reliable short-circuit protection

by reacting within milliseconds. Closecoupling adaptors are available for

combination with ABB contactors.
