170M5208

170M5208 Application Field and Working Principle

The 170M5208 family of fuses are designed for applications requiring low operating voltages and higher breaking capacity. Typically used in medium voltage switchgear and transformers, these fuses offer superior operational safety, making them a popular choice for residential and commercial applications alike.

Features of the 170M5208 Fuses

• High breaking capacity
• 360° viewable label for maximum visibility
• 80% MCOV rating
• Individually boxed for easy installation

Panel Mounting of the 170M5208 Fuses

The 170M5208 family of fuses are available in both panel mount and direct mount options. For panel mounted applications, the fuse body is mounted in an appropriate sized cutout in the panel using a retainer clip or other suitable fastener. The fuse body should be mounted flush with the surface of the panel and the entire circuit should be made accessible for service.

Operating Principle of the 170M5208 Fuses

The fuses of the 170M5208 family are current limiting fuses that are designed to open in order to protect circuits, equipment, or components from overloads and short circuits. The fuses are constructed with a semiconductorifying element, fuse blade, and housing. When the current in the circuit rises to a certain level, the fuse element melts and the fuse opens, disrupting the circuit.

Fuse Time-Current Characteristic Curve

The time-current characteristic curve of a fuse shows how fast the fuse will open at various current levels. The time-current characteristic curve of the 170M5208 fuses show that these fuses will open in a fraction of a second when exposed to short-term overloads. For longer-term overloads, the fuses will open in a matter of minutes.

Applications of the 170M5208 Fuses

The 170M5208 family of fuses are typically used in medium voltage switchgear and transformers. These fuses are designed for low-voltage applications and offer superior operational safety. They are also suitable for residential and commercial applications such as lighting, security systems, and motor control.
