The Bussmann LPN-RK-20SP Low-Peak™ Dual-Element Time-Delay Fuse is engineered to deliver superior protection for electrical systems, particularly in large distribution switchboards, power panelboards, motor control centers, and machinery disconnect switches.
Key Features
- Dual-Element Design: Provides fast short-circuit protection combined with time-delay performance, ensuring optimal safety and reliability.
- High Interrupting Capacity: Rated at 300,000 amperes for 250 VAC and 100,000 amperes for 125 VDC, offering robust protection against high fault currents.
- Current-Limiting Capability: Minimizes the let-through energy during fault conditions, safeguarding downstream components from potential damage.
- Time-Delay Feature: Allows sizing up to 130% of motor full load amps (FLA) for backup overload protection, accommodating high inrush currents typical in motor applications.
- Selective Coordination: Simplifies system design with a consistent 2:1 ampacity ratio, facilitating easy coordination with other Low-Peak™ fuses.
- Reduced Inventory Needs: Upgrading to Low-Peak™ fuses can decrease existing fuse inventory by up to 33%, streamlining maintenance and replacement processes.
- Enhanced Safety: Electrically isolated end caps provide additional safety during installation and operation.
