Product Positioning

The 3RW5245-6AC14 is a SIRIUS 3RW52 series soft starter with a rated current of 315A. It provides analog output signals and can transmit information such as operating current for use by upper-level monitoring systems. It is suitable for medium and large three-phase motor applications that require real-time monitoring of motor operating status.

Core Product Advantages and Features

Analog output real-time monitoring

The default output is 4-20mA signal, and it can also be set to 0-10V via the High Feature HMI.

Multiple digital output contacts

It is equipped with two sets of normally open digital outputs and one set of switching contacts, which facilitates the connection of alarms or interlocking circuits.

Medium and high current starting capability

With a rated current of 315A, it is suitable for the slow start and slow stop control of medium and large three-phase motors.

Built-in bypass connection design

After startup, it switches to bypass operation to improve system efficiency and reduce the body's heat generation.
