Reliance Electric ECNR-30 Series RK5 Time-Delay Fuse Dual Element 30A 250V AC/DC
The Reliance Electric ECNR-30 Series RK5 Time-Delay Fuse is a dual-element fuse designed to provide superior protection for electrical circuits, particularly those with inductive loads such as motors and transformers. With a 30-ampere rating and a voltage capacity of 250V AC and 125V DC, this fuse is suitable for a wide range of industrial applications.
Key Features
- Dual-Element Design: Offers enhanced overload and short-circuit protection by utilizing two separate elements within the fuse.
- Time-Delay Capability: Allows the fuse to withstand temporary inrush currents, such as those experienced during motor startups, without unnecessary openings.
- High Interrupting Rating: Capable of interrupting fault currents up to 200,000 amperes, ensuring robust protection for electrical systems.
- Current Limiting: Reduces the let-through energy during a fault condition, minimizing potential damage to downstream equipment.
- Compliance with Standards: Meets UL 248-12 and CSA C22.2 standards, ensuring reliability and safety in various applications.
Specifications
- Amperage Rating: 30 A
- Voltage Rating: 250 V AC / 125 V DC
- Interrupting Rating: 200 kA at 250 V AC
- Response Time: 8 seconds at 500% of rated current
- Fuse Class: RK5
- Terminal Type: Ferrule
- Dimensions: 0.56 inches in diameter, 2 inches in length
Applications
This fuse is ideal for use in AC power distribution system mains, feeders, and branch circuits with inductive loads such as motors and transformers. It is also suitable for non-inductive loads like lighting and heating systems. The time-delay feature allows for closer sizing to the running ampacity of inductive loads, reducing costs and improving overcurrent protection.
Benefits
- Enhanced Motor Protection: Protects motors against burnout from overloads and single-phasing on three-phase systems.
- Improved System Reliability: Helps prevent unnecessary downtime by allowing temporary overloads without opening.
- Cost Efficiency: Allows for smaller fuse sizing, reducing costs while maintaining protection.
The Reliance Electric ECNR-30 Series RK5 Time-Delay Fuse is a reliable and cost-effective solution for protecting electrical circuits in industrial settings, offering both high performance and compliance with industry standards.
