3RW4444-6BC44

The 3RW4444-6BC44, part of Siemens' SIRIUS series, is a robust soft starter engineered for a variety of motor control applications. Capable of handling an insulation voltage rated at 690 V, this unit efficiently manages an operational current of 250 A. Within its operating specifications, the soft starter supports voltage levels between 200 and 460 V and functions effectively across frequencies of 50 to 60 Hz.

A minimum load requirement of 8% allows for operational flexibility, while the device maintains a power loss of 110 W during standard function. The dimensions of the soft starter measure 210 mm in width, 230 mm in height, and 298 mm in depth, providing a compact design for space-constrained environments.

The utilization of screw fixing ensures a secure installation, and the unit must be mounted vertically to adhere to operational guidelines. The 3RW4444-6BC44 can accommodate cable lengths of up to 500 m, making it suitable for extensive installations.

The soft starter is designed to operate at high altitudes, with an installation capability of up to 5,000 m above sea level. It is rated at IP00, indicating that it is designed for use in protected environments. The derating temperature of 40 degrees Celsius further underscores its reliability in diverse operating conditions.
