The FDB2020S18 is a molded case circuit breaker manufactured by Eaton/Cutler-Hammer. It is designed to provide overcurrent and short-circuit protection for electrical circuits in commercial and industrial applications. This breaker is part of Eaton's Series C line, known for its reliability and performance. It is a thermal-magnetic breaker, meaning it uses a thermal element for overload protection and a magnetic element for short-circuit protection.

Applications

• Panelboards and switchboards: Used as main or branch circuit breakers in electrical distribution panels.
• Motor control centers (MCCs): Provides overcurrent protection for motor circuits.
• Individual equipment protection: Protects specific electrical equipment from overloads and short circuits.
• Feeder circuits: Used as feeder breakers to protect downstream circuits.
• Branch circuits: Protects individual branch circuits supplying power to lighting, receptacles, and other loads.

Features

• Thermal-magnetic trip mechanism: Provides both overload and short-circuit protection.
• Molded case construction: Offers rugged protection for internal components.
• Fixed trip settings: Non-adjustable trip settings for reliable performance.
• Interrupting rating: High interrupting rating to safely interrupt fault currents.
• Series C design: Part of Eaton's reliable and widely used Series C line of circuit breakers.

Benefits

• Reliable protection: Ensures reliable protection against overcurrents and short circuits.
• Durable construction: Provides long-lasting performance in demanding environments.
• Easy installation: Simple to install and connect in various electrical systems.
• Compliance with standards: Meets industry standards for safety and performance.
