Eaton Bussmann FNQ-1 Low Voltage Fuse

Product Description - FNQ-1 - Eaton Low Voltage Fuse

Eaton Bussmann series FNQ fuse, Time-delay, Motor control transformers, Circuits with in-rush currents, 1 A, Non-indicating, Ferrule end x ferrule end, 10 kAIC at 500 Vac, Nickel-plated bronze endcap, Standard, 500 V

The Eaton Bussmann series FNQ-1 fuse is a time-delay fuse specifically designed for use in motor control transformers and circuits that experience in-rush currents. Its primary function is to protect electrical equipment from damage caused by excessive currents, particularly during start-up or transient conditions.

Key Features and Specifications:

• Type: Time-delay fuse, suitable for applications where a brief surge of current (in-rush current) occurs during start-up or operation.
• Application: Ideal for motor control transformers and circuits that encounter in-rush currents.
• Current Rating: 1 Ampere (A), ensuring accurate protection against overcurrent conditions within the specified range.
• Indication: Non-indicating, meaning it does not have a visual indicator to show when the fuse has blown.
• Terminals: Ferrule end x ferrule end, providing a reliable and secure connection to the circuit.
• Interrupting Rating: 10,000 Amperes at 500 Volts AC (10 kAIC at 500 Vac), indicating its ability to safely interrupt a fault current of up to 10,000 A under specified conditions.
• Endcap Material: Nickel-plated bronze, enhancing corrosion resistance and ensuring durability.
• Standard Compliance: Designed to meet industry standards, ensuring compatibility and reliability in a wide range of applications.
• Voltage Rating: 500 Volts, suitable for use in circuits with operating voltages up to 500V.

Benefits:

• Time-delay Characteristic: Prevents nuisance tripping due to brief in-rush currents, allowing motors and transformers to start up smoothly.
• High Interrupting Capacity: Ensures safe and reliable operation even in fault conditions, minimizing the risk of damage to equipment and personnel.
• Corrosion-resistant Endcaps: Prolongs fuse life and maintains electrical integrity, even in harsh environments.
• Compact Design: Facilitates easy installation and integration into existing electrical systems.

The FNQ-1 fuse from Eaton Bussmann is a reliable and efficient solution for protecting motor control transformers and circuits against damaging overcurrent conditions, particularly those involving in-rush currents. Its time-delay characteristic, high interrupting capacity, and corrosion-resistant design make it an ideal choice for a wide range of industrial and commercial applications.
