FLSR012 - 12 Amp Fuse

FLSR012 - 12 Amp Fuse

When a circuit calls for a 12-amp Class RK5 time-delay fuse, the FLSR012 provides the electrical characteristics needed for demanding industrial and commercial applications. This dual-element cartridge fuse is rated for 12A continuous current, up to 600VAC and 300VDC, and uses a Slo-Blo/time-delay design. Installation is through a compatible fuse block, clip, or holder, including the specified LFR60030 Series holder. Whether you're maintaining existing electrical equipment or replacing a fuse with matching specifications, the FLSR012 offers a straightforward 12A, 600V Class RK5 fuse with time-delay performance designed for real-world electrical applications.

Key Features and Benefits

• 12A continuous current rating for equipment and circuits requiring 12-amp overcurrent protection.
• Rated up to 600VAC, making it suitable for compatible higher-voltage AC systems.
• A 300 VDC maximum rating expands its usefulness for qualifying DC applications.
• Time-delay / Slo-Blo operation allows the fuse to handle temporary current surges without opening unnecessarily.
• Its dual-element design provides time-delay characteristics while maintaining overcurrent protection.
• Class RK5 construction is designed for applications specifically suited to this fuse class.
• Industrial cartridge format works with the appropriate fuse block, clip, or holder.

Material Compliance and Certifications

The supplied specifications do not provide detailed information on material composition, environmental compliance, or certification for the FLSR012. If your installation has specific regulatory, environmental, or material-compliance requirements, confirm the applicable documentation for this exact catalog number before putting the fuse into service.

Where It Works Best

The FLSR012 makes the most sense in industrial or commercial equipment that specifically requires a 12A Class RK5 time-delay fuse. Its time-delay characteristics are particularly useful in circuits that may experience a temporary surge during normal equipment startup. In those situations, an instantaneous response isn't always desirable.

It can also be a practical replacement for an existing FLSR012 when the equipment specifications match. With its 600VAC rating, 300VDC capability, dual-element construction, and high AC interrupting capacity, it covers a useful range of compatible electrical applications without making the selection process more complicated than necessary.
