Product Description:

The Danfoss 175G5541 is a VLT® Soft Starter MCD 500 for high power industrial motor control. This soft starter gives controlled acceleration and deceleration for motors up to 315 kW, preventing mechanical shock and electrical stress during start and stop cycles. It is designed to eliminate the harsh transitions associated with direct-on-line starting, protecting both the motor and connected mechanical equipment from inrush currents. By giving gradual speed transitions the starter extends equipment life and reduces maintenance across heavy duty applications like compressors and conveyor systems.

The 175G5541 has Adaptive Acceleration Control that adjusts starting parameters based on load conditions and automatically optimizes performance for varying operational demands. Operating in a voltage range of 200-525 VAC with a rated current of 595A, this soft starter is for high power motor applications with high reliability. It has dual control voltage options of 110 VAC and 220 VAC, giving installation flexibility across different electrical infrastructure. The starter comes equipped with advanced motor protection algorithms to monitor operational parameters. This helps to prevent damage from overcurrent, phase loss and thermal overload.

The 175G5541 has a bypass contactor system that allows continuous operation without internal bypass contacts. This helps to reduce heat generation and improves overall system efficiency during normal running conditions. The G4 frame size 4 enclosure has enough space for proper heat dissipation and is compact enough for industrial installation. This bypass configuration means once the motor is up to speed, current flows directly through the bypass contactor instead of the soft starter’s power electronics, minimizing energy loss. The unit comes in a modular design for easy maintenance. It can be integrated with existing motor control systems. The starter allows remote monitoring and diagnostics, supporting predictive maintenance for reduced downtime.
