Siemens 3RW4928-8VB00 ET 200SP Motor Starter

The Siemens 3RW4928-8VB00 acts as a critical thermal management accessory for industrial motor control. This cooling fan specifically targets the SIRIUS 3RW402 soft starter series. It facilitates active heat dissipation during intensive operation. By maintaining lower internal temperatures, the unit prevents premature component aging. Consequently, the fan significantly extends the service life of the soft starter hardware.

Engineers typically install this module in high-density ET 200SP motor starter configurations. In these environments, stagnant air often leads to thermal tripping. This fan provides the necessary airflow to maintain continuous performance under heavy loads. It supports 400 V AC power systems effectively.

Key Technical Specifications

Installation and System Integration

The 3RW4928-8VB00 features a streamlined mechanical design for rapid integration. Users can attach the fan directly to the soft starter housing. This plug-and-play approach minimizes installation time during system assembly. The hardware remains robust even in high-vibration industrial settings. Furthermore, its compact profile ensures it fits within standard control cabinets.

This accessory maintains high reliability for critical machinery. It serves essential roles in pumping stations and compressor systems. Additionally, conveyor applications benefit from the consistent cooling during frequent start-stop cycles. Proper ventilation ensures the soft starter maintains its current carrying capacity without derating.
