FLSR100-ID - 100 Amp Fuse

FLSR100-ID - 100 Amp Fuse

When a motor is running, it doesn't constantly draw the same amount of current. Take startup, for instance: during those first moments, the current can surge far above the normal levels, but that’s not necessarily a sign of trouble. This is where the FLSR100-ID comes into play. This 100A Class RK5 dual-element fuse is specifically designed to handle those brief spikes with its time-delay response. It allows for those short-term inrush currents while still providing solid protection against ongoing overloads and short circuits. It’s a smart choice for keeping your motor safe and functioning smoothly.

Key Features and Benefits

• 100A continuous rating for circuits designed around 100-amp fuse protection.
• Class RK5, dual-element construction with time-delay operation.
• Handles appropriate, short-lived inrush current without sacrificing protection against sustained overcurrent conditions.
• Rated up to 600VAC and 300VDC.
• Indicating design helps make an open fuse easier to identify during troubleshooting.
• Knife-blade style fits the appropriate fuse block, clip, or holder.
• LFR60100 Series PG holder is specified for compatible installations.

Material Compliance and Certifications

The FLSR100-ID is a Class RK5 fuse, but that designation is only one part of choosing the correct fuse for a circuit. The 100A rating, voltage, interrupting capacity, time-delay characteristics, and physical configuration must also match the equipment requirements.

If your project requires documentation for specific UL, CSA, RoHS, REACH, environmental, or material compliance requirements, check the current documentation for the FLSR100ID itself. It's better to confirm the exact catalog number than to assume every fuse in the same product family carries identical documentation.

Where It Works Best

The FLSR100-ID is especially relevant when the load doesn't behave like a simple, steady current draw. Motors and transformers are good examples. Both can experience a noticeable surge when they're first energized, followed by a lower current once normal operation begins.

Depending on the equipment design and protection requirements, the FLSR100-ID may be used in motor circuits, transformer applications, motor-control equipment, industrial machinery, feeders, switchboards, service equipment, and power-distribution systems calling for its ratings and Class RK5 characteristics.
