The Siemens 3RW4928-8VB00 provides essential active cooling for SIRIUS 3RW402 (Size S0) soft starters. This high-efficiency fan prevents overheating in ET 200SP motor systems, supporting higher starting frequencies and extended hardware life.
Engineers specifically utilize the Siemens 3RW4928-8VB00 to manage thermal loads within SIRIUS 3RW402 (Size S0) soft starters. This high-efficiency cooling fan actively prevents heat accumulation during high-frequency switching and heavy-load motor starts. By maintaining precise internal temperatures, the module stabilizes the solid-state power electronics, ensuring the long-term reliability of the ET 200SP motor starter environment.
The fan unit integrates directly into the soft starter housing, which delivers a streamlined cooling solution without expanding the control cabinet’s physical footprint. This direct integration facilitates rapid heat dissipation, allowing the system to handle higher starting frequencies while providing an essential protective layer against thermal tripping. Consequently, the 3RW4928-8VB00 secures sensitive automation networks against heat-induced interruptions.
Industrial facilities deploy this cooling fan across various applications, including conveyor systems, centrifugal pumps, and industrial compressors. The robust German engineering guarantees full compatibility with 400V AC systems. Ultimately, this vital peripheral empowers engineers to extend the service life and operational consistency of their Siemens SIRIUS soft starter hardware.

The Bently Nevada 21000-16-05-00-115-03-02 is a rigid proximity probe housing assembly engineered to provide a secure and stable mounting for eddy current proximity probes used in machinery protection systems. Its primary function is to physically protect the probe while positioning it at a precise, fixed distance from the observed machine shaft or target surface. This specific assembly, constructed from 303 stainless steel, ensures mechanical integrity and corrosion resistance in harsh industrial environments. It integrates as a critical front-end mechanical component for systems like the Bently Nevada 3500. While the housing itself is a passive component and does not transmit an electrical signal, its dimensional accuracy is fundamental for the integrity of the measurement chain. By holding the probe stationary relative to the machine casing, it enables the connected Proximitor Sensor and monitor to accurately measure radial vibration, axial thrust position, and phase reference (Keyphasor) data. The 1.6-inch penetration length and 1-1/4 - 12 UNF mounting thread are specified for direct installation into pre-drilled and tapped holes on machine casings.

In Oil & Gas and Power Generation applications, the 21000-16-05-00-115-03-02 housing assembly demonstrates high reliability on critical rotating machinery such as gas and steam turbines, centrifugal compressors, and boiler feed pumps. Its rigid, single-piece 303 stainless steel construction provides excellent resistance to mechanical vibration and thermal expansion, ensuring measurement stability and data integrity for the connected condition monitoring system. The material specification offers robust protection against corrosion from hydrocarbons, process chemicals, and atmospheric moisture. As a passive mechanical component, its Mean Time Between Failures (MTBF) is exceptionally high, with reliability being primarily dependent on correct installation and torque procedures. The specified operating temperature range of -51°C to +177°C allows for direct mounting on hot machine casings without degradation of its mechanical properties, making it suitable for a wide spectrum of industrial operating conditions.
Q: What systems is the 21000-16-05-00-115-03-02 compatible with?
A: The 21000-16-05-00-115-03-02 is designed as a front-end component for Bently Nevada's 3500 and 3300 Machinery Protection and Condition Monitoring Systems. It is mechanically compatible with any system utilizing Bently Nevada 3300 XL 8mm, 3300 8mm, or 7200 series (5mm and 8mm) proximity probes. Its function is purely mechanical, so electrical compatibility is determined by the probe, extension cable, and Proximitor sensor it is used with.
Q: What are the installation requirements?
A: Installation requires a pre-drilled and tapped hole in the machine casing with a 1-1/4 - 12 UNF thread. The housing is threaded into this mount point. The proximity probe is then inserted into the housing and its axial position is adjusted to set the correct DC gap voltage relative to the shaft
