Bussmann LPS-RK-90SP Time Delay Fuse

Optimal Circuit Protection with Precision Delay

Overview

The Bussmann LPS-RK-90SP is a high-performance time-delay fuse designed for reliable overcurrent protection in demanding electrical systems. Engineered for compatibility with 90-ampere circuits, this fuse combines robust interrupting capacity with selective coordination to safeguard motors, transformers, and sensitive branch circuits. Its dual-element design ensures immunity to nuisance tripping during harmless inrush currents while delivering rapid response to genuine fault conditions.

Key Features

  • Time-Delay Functionality
    Tolerates temporary startup surges (e.g., motor inrush) without interruption, minimizing operational downtime.
  • High Interrupting Rating
    200kA breaking capacity at 600V AC, ensuring reliable protection against short circuits and overloads.
  • Class RK5 Compliance
    Compact dimensions (1-1/2″ x 13/32″) allow drop-in replacement in existing Class RK fuseholders, saving retrofit costs.
  • Dual-Element Construction
    Thermal-responsive element for overloads + fast-acting link for short circuits—optimizing safety without false trips.
  • Tin-Plated Terminals
    Corrosion-resistant contacts maintain conductivity and longevity in humid or industrial environments.

Applications

Ideal for:

  • Motor control centers (MCCs)
  • HVAC systems & industrial machinery
  • Power distribution panels
  • Transformers and feeder circuits
  • Branch circuits requiring coordination with upstream protection
