FN351H-50-33 SCHAFFNER Inductors Coils Filters

Review SCHAFFNER

The Schaffner FN351-H-50-33 filter is a crucial component in power distribution systems, designed to ensure the reliable and efficient operation of electrical equipment. This filter is part of Schaffner's FN351-H series, known for their high-performance and robust design.

The Schaffner FN351-H-50-33 is a 50 kVA, 3-phase filter with a rated voltage of 480V. It is designed to filter harmonic currents and reduce electromagnetic interference (EMI) and radio-frequency interference (RFI) in industrial power systems. The filter is constructed with high-quality materials, including a steel housing that ensures durability and resistance to harsh environments.

This filter is equipped with metal-oxide varistors (MOVs) as the primary harmonic filtering component. The MOVs are designed to clamp voltage spikes and provide protection against overvoltages. The filter also includes tuned reactive components, such as inductors and capacitors, that are tuned to specific harmonic frequencies to provide optimal filtering performance.

The Schaffner FN351-H-50-33 filter is designed with a compact, modular construction that makes installation and maintenance easy. It is also designed to be easily paralleled with other filters for larger installations. The filter is equipped with a maintenance-free, self-healing fuse that provides overload protection and ensures the safety of the filter and connected equipment.

In addition to its filtering capabilities, the Schaffner FN351-H-50-33 also provides excellent EMI and RFI suppression. The filter meets the requirements of IEC 61000-3-2 and IEC 61000-3-3 for EMI and RFI emissions and immunity, respectively. It also meets the requirements of IEEE Std. 519-1992 for harmonic current limiting and IEEE Std. 61850-27-12 for communication network protection.

Overall, the Schaffner FN351-H-50-33 filter is a high-performance, reliable, and robust component that is essential for ensuring the efficient and reliable operation of industrial power systems. Its advanced filtering capabilities, compact design, and ease of installation make it a popular choice for a wide range of applications.

The Schaffner FN351-H-50-33 and FN351H-50-33 are both current limiter models from Schaffner Electric. These devices are used to limit the current flow in an electrical circuit to protect against overloads and short circuits. Below are some pros and cons of buying these specific models.

1. High Protective Capacity: Both models offer a high protective capacity, making them suitable for applications with high current demands.

2. Wide Operating Temperature Range: The devices can operate in a wide temperature range, which increases their versatility in various applications.

3. High Reliability: Schaffner Electric is known for producing high-quality and reliable current limiter products.

4. Robust Design: These models have a robust design that can withstand harsh environments, making them suitable for industrial applications.

5. Easy to Install: The devices come with a simple and straightforward installation process, which saves time and reduces the installation cost.

1. Cost: The Schaffner FN351-H-50-33 and FN351H-50-33 are more expensive compared to other current limiter models from other brands.

2. Size: These models are larger in size compared to other current limiter models in the market, which may require more space for installation.

3. Limited Compatibility: These models may not be compatible with all types of electrical systems, so it's essential to check the specifications before making a purchase.

The Schaffner FN351-H-50-33 and FN351H-50-33 are reliable and robust current limiter models suitable for applications with high current demands and harsh environments. However, their high cost and size may be a disadvantage for some users. If the application requirements align with the advantages of these models, then the investment in a Schaffner current limiter is a worthwhile one.

If the application requirements don't require the high protective capacity or harsh environment compatibility of the Schaffner FN351-H-50-33 and FN351H-50-33, it may be worth considering other current limiter models from other brands that offer a lower cost and smaller size. However, if the application demands a high protective capacity and can accommodate the larger size and higher cost, then the Schaffner models are a solid investment.
