FLSR004-ID - 4 Amp Fuse

FLSR004-ID - 4 Amp Fuse

The FLSR004-ID is a 4-amp, 600VAC Class R fuse designed for your applications that require dependable overcurrent protection without nuisance tripping during normal, short-term current surges. Its time-delay design makes it a practical fit for circuits where startup or inrush current is expected. At the same time, its current-limiting characteristics protect in the event of a serious fault. With an interrupting rating of 200 kA at 600 VAC, the FLSR004-ID is suited to electrical systems where the available fault current can be significant. This is a cartridge-style, non-indicating fuse, measuring approximately 5 inches long by 0.81 inches wide and 0.81 inches deep.

Key Features and Benefits

• 4 amp rating for compatible low-amperage circuit protection applications.
• Rated for electrical systems up to 600VAC.
• Time-delay operation accommodates appropriate temporary current surges without unnecessarily opening the circuit.
• Current-limiting design helps reduce the amount of fault current that can pass through the circuit during qualifying fault conditions.
• Class R configuration for equipment designed to use this fuse class.
• Straightforward cartridge-style construction for compatible fuse holders.
• Non-indicating design without an integral blown-fuse indicator.

Material Compliance and Certifications

The supplied specifications identify the FLSR004-ID as a Class R current-limiting fuse. Specific UL, CSA, RoHS, REACH, or other certification and material-compliance information was not provided for this listing. When a particular approval or compliance standard is required for a project, verify it against the applicable manufacturer documentation before installation.

Where It Works Best

The FLSR004-ID is suitable for commercial and industrial electrical systems that require a 4A Class R time-delay fuse. Its time-delay characteristic is particularly useful where a circuit may see a brief rise in current during normal operation, such as the inrush associated with compatible motors, transformers, control equipment, and other inductive loads.

It's also a solid choice when you're replacing an existing fuse with these same electrical and physical specifications. Check more than just the amperage before making a match: 600 VAC rating, Class R construction, 200 kA interrupting rating, time-delay operation, current-limiting characteristics, and dimensions all matter. That extra check helps ensure the replacement is appropriate for the equipment and the circuit's protection requirements.
