Edison LESRK-4-1/2 4.5A Time-Delay Class RK1 Current-Limiting Fuse (Lot of 3)

The Edison LESRK-4-1/2 is a 4.5-amp, dual-element, time-delay fuse designed for superior protection in AC power distribution systems. This Class RK1 fuse operates at up to 600 VAC and offers a high interrupting rating of 200,000 RMS symmetrical amperes, ensuring robust defense against short-circuit events.

Key Features

• Dual-Element Design: Allows for sizing at 125% of full load amperes (FLA), providing effective motor backup protection.
• Time-Delay Capability: Withstands high inrush currents, making it ideal for motor and transformer applications without nuisance tripping.
• Current-Limiting: Offers up to 40% more current limitation and up to 350% more I²t limitation under fault conditions compared to standard fuses, reducing potential equipment damage.
• High Interrupting Rating: Rated at 200 kA RMS symmetrical, ensuring reliable performance in high-fault current scenarios.
• Compliance and Certification: UL Listed (Class RK1, Guide JDDZ, File E162363) and CSA Certified (HRCI-R per C22.2, No. 248.12), meeting stringent safety standards.

Applications

Ideal for use in AC power distribution system mains, feeders, and branch circuits, the LESRK-4-1/2 fuse is suitable for both general-purpose applications, including lighting and heating, as well as motor protection scenarios. Its time-delay feature permits sizing at 130% of FLA, offering backup protection against single-phase damage.
