Starter system, direct MSC-D-4-M7(230V50HZ) 283143

Motor starter unit – reliable start and protection

This pre-assembled motor starter unit, consisting of a contactor and a motor protective circuit breaker, is designed to minimize wiring time and ensure reliable operation. It is an ideal solution for both professional installers and end-users looking for a simple to install and safe starting system. The device is intended for direct-on-line motor starting, offering effective protection against overloads and short circuits.

Key features and application

The MSC-D-4-M7(230V50HZ) starter unit from Eaton is a component dedicated to controlling motors up to 1.5 kW (AC-3, 400V). The rated operating current of 3.6A ensures compatibility with a wide range of industrial applications. The built-in short-circuit release and the adjustable overload release range (2.5 - 4A) guarantee installation safety and protect the motor from damage. Using this unit allows for efficient motor starting in various operating conditions.

Technical parameters and construction

The device is characterized by compact dimensions – 45 mm width, 180 mm height and 95 mm depth – which facilitates mounting even in limited spaces. Made of high-quality materials, it ensures durability and reliable operation. Screw connections of the main and auxiliary circuit simplify the installation process. Protection class IP20 indicates protection against accidental contact and the ingress of solid objects larger than 12.5 mm. Overload protection with temperature compensation ensures stable operation in varying ambient conditions. The unit has a release class of 10, which means a standard time-current characteristic. The rated conditional short-circuit current of 50 kA (type 2) provides effective protection in the event of a short circuit in the installation. The unit's power consumption is only 1.4W, which translates to low operating costs.
