FLSR175 - 175Amp Fuse

FLSR175 - 175Amp Fuse

When your application calls for a 175-amp, 600V AC Class R fuse, getting the details right matters. The FLSR175 is a knife-blade, non-indicating, time-delay current-limiting fuse rated at 175A, with a 200 kA interrupting rating at 600V AC. Its time-delay characteristic is especially useful in properly matched electrical equipment where brief inrush or startup currents are expected during normal operation.

Key Features and Benefits

• 175A current rating – Sized for equipment and circuits specifically requiring a 175-amp fuse.
• Rated for 600V AC – Suitable for compatible AC electrical systems operating within the fuse's voltage rating.
• Time-delay operation – Allows the fuse to tolerate appropriate temporary inrush current without opening simply because of a brief, normal current surge.
• Current-limiting Class R fuse – Combines Class R construction with current-limiting performance for correctly specified electrical protection applications.
• Knife-blade style – Intended for compatible fuse blocks, clips, and holders designed for this physical configuration.

Where It Works Best

The FLSR175 makes sense in electrical equipment that specifically calls for a 175A, 600V AC, time-delay Class R fuse with a knife-blade configuration. Its time-delay behavior is particularly relevant where properly applied equipment experiences a brief rise in current during normal startup or operation.
