FLNR175-ID - 175 Amp Fuse

FLNR175-ID - 175 Amp Fuse

The FLNR175-ID is a 175-amp Class RK5 time-delay fuse designed for electrical applications where dependable overcurrent protection and easy identification of fuse status are important. Its dual-element, Slo-Blo/time-delay design allows the fuse to tolerate temporary current surges that can occur during normal equipment startup while still protecting sustained overcurrent conditions. Whether you're replacing an existing FLNR175-ID or matching a fuse to specified equipment requirements, this model combines time-delay performance, high interrupting capacity, and visual indication in a single practical fuse.

Key Features and Benefits

Material Compliance and Certifications

The FLNR175-ID is identified as a Class RK5 fuse. The supplied product specifications do not include specific RoHS, REACH, lead-free, or other material compliance declarations for this exact catalog number. For installations subject to specific regulatory, environmental, or material requirements, verify the applicable certification and compliance documentation for the exact FLNR175-ID before installation.

Where It Works Best

The FLNR175-ID is a practical choice for industrial and commercial electrical applications requiring 175A Class RK5 time-delay overcurrent protection. Its time-delay characteristics are particularly valuable in circuits where equipment can draw a temporary current surge during startup. Rather than reacting to every short-duration inrush condition, the fuse is designed to accommodate these normal operating events while protecting the circuit from sustained overcurrent.

This combination makes the FLNR175-ID a strong fit for compatible motor circuits, transformers, industrial equipment, machinery, and electrical distribution applications where the equipment specifications call for its ratings and fuse class. The indicating feature offers another useful advantage in environments where reducing troubleshooting time matters, as personnel can more easily determine the fuse status during maintenance.
