Bullet ECSR50 Time Delay Class RK5 600V Fuse

Bullet ECSR50 Time Delay Class RK5 600V Fuse

The Bullet ECSR50 is a 50-ampere, 600-volt, Class RK5 time-delay fuse designed to provide reliable overcurrent protection in various electrical applications. Its dual-element construction allows it to handle temporary inrush currents, making it ideal for circuits with inductive loads such as motors and transformers.

Key Features

• Amperage Rating: 50 A
• Voltage Rating: 600 VAC
• Interrupting Rating: 200 kAIC
• Class: RK5
• Time-Delay Response: 10 seconds at 500% of rated current
• Construction: Dual-element, current-limiting design
• Body Material: Fiberglass
• Dimensions: 1.06 inches in diameter, 5.5 inches in length

Applications

The ECSR50 fuse is suitable for a wide range of applications, including:

• AC power distribution system mains, feeders, and branch circuits
• Protection of motors and motor branch circuits
• Transformers and other inductive loads
• Lighting, heating, and other non-inductive load applications

Benefits

• Provides motor overload, ground fault, and short circuit protection
• Allows sizing closer to full load amps for maximum overcurrent protection
• Reduces unnecessary fuse openings by overriding normal equipment current surges
• Offers moderate current limitation for enhanced safety

The Bullet ECSR50 fuse combines robust protection with time-delay characteristics, making it a reliable choice for safeguarding electrical systems against overcurrent conditions.
