Starting system, direct MSC-D-12-M12(230V50HZ) 283148

Motor starter unit – reliable start and protection

This direct-on-line starter unit, designated MSC-D-12-M12(230V50HZ), is a ready-to-use solution for starting electric motors. Composed of a motor starter and contactor, it minimizes wiring time and provides comprehensive protection. It is an ideal choice for both professional installers and end-users looking for a reliable and safe system.

Design and operating parameters

The starter unit is characterized by its compact dimensions – 45 mm width, 180 mm height, and 95 mm depth. It is designed to operate in 230V/50Hz networks and does not require a transformer. The rated operating power for AC-3 is 5.5 kW at 400V and 3 kW at 230V, and the rated operating current is 11.3 A (AC-3, 400V). It is worth noting the setting range of the overload release – from 8 to 12 A, which allows adaptation to different loads. Overload protection with temperature compensation ensures stable operation in varying ambient conditions.

Safety and protection

The unit is equipped with a built-in short-circuit release, which effectively protects the circuit against the effects of short circuits. Additionally, it has overload protection, which prevents damage to the motor in the event of excessive load. The release class is CLASS 10 A, and the rated conditional short-circuit current (Type 2 coordination) is 50 A at 400 V. The IP20 degree of protection provides basic protection against contact and ingress of solid objects. Coordination according to IEC 60947-4-3 meets the requirements of Class 1, guaranteeing a high level of installation safety.

Installation and application

The starter unit with screw connections, main and auxiliary, facilitates quick and secure installation. The lack of the possibility of mounting on a rail provides flexibility in choosing the installation location. The device is intended for direct starting of electric motors and finds application in various industrial and construction applications. The maximum ambient operating temperature is 55°C.
