The Bullet ECSR50 is a 50-amp, 600-volt, dual-element, time-delay fuse designed for superior protection in AC power distribution systems. As a Class RK5 fuse, it offers a high interrupting rating of 200,000 amperes RMS symmetrical, ensuring reliable performance in demanding applications. Key Features Dual-Element Design: Provides both short-circuit and overload protection, allowing the fuse to handle temporary inrush currents without unnecessary openings. Time-Delay Capability: Offers a minimum time-delay of 10 seconds at 500% of the rated current, making it suitable for circuits with inductive loads such as motors and transformers. High Interrupting Rating: Withstands up to 200,000 amperes RMS symmetrical, ensuring safety and reliability in high-fault current scenarios. Versatile Application: Ideal for protecting mains, feeders, and branch circuits in systems with both inductive and non-inductive loads. Standard Dimensions: Measures 5.5 inches in length and 1.06 inches in diameter, facilitating easy installation in compatible fuse holders. Applications The ECSR50 fuse is recommended for use in: 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 Specifications Amperage Rating: 50 A Voltage Rating: 600 V AC Interrupting Rating: 200 kAIC Response Time: 10 seconds at 500% of rated current Fuse Class: RK5 Fuse Indicator: Non-indicating End Connections: Ferrule end x ferrule end Dimensions: Length: 5.5 inches; Diameter: 1.06 inches The Bullet ECSR50 fuse combines robust protection with time-delay functionality, making it a reliable choice for safeguarding electrical systems against overloads and short circuits.
