Data sheet Manual motor starter MS325 Description -- Overload protection - trip class 10A -- Phase loss sensitivity -- Disconnect function -- Temperature compensation from -25 ... +50 C -- Adjustable current setting for overload protection -- Suitable for three- and single-phase application -- Trip-free mechanism -- Clear switch position indication ON/OFF 2CDC241500S0009 Manual motor starters are electro mechanical protection devices for the main circuit. They are used mainly to switch motors manually ON/OFF and protect them fuse less against short-circuit, overload and phase failures. Fuse less protection with a manual motor starter saves costs, space and ensures a quick reaction under shortcircuit condition, by switching off the motor within milliseconds. Fuse less starter combinations are setup together with contactors.

They are three pole protection devices with thermal tripping elements for overload protection and electromagnetic tripping elements for shortcircuit 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 the direct adjusting 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 (no tripping at 1.05 x I, tripping at 1.2 x I; I = setting current). 2CDC242024F0009 2CDC242023F0009 Operation mode Single-phase operation Three-phase operation 2CDC242025F0009 Wiring diagram 2 -
