The 0460.500UR is a 500mA, 250V, time-delay fuse manufactured by Littelfuse Inc. This fuse is designed to provide overcurrent protection in circuits where temporary inrush currents are common. Its time-delay characteristic allows it to withstand these inrush currents without nuisance tripping, while still providing reliable protection against sustained overloads and short circuits.

Applications:

• Power Supplies: Protects power supply circuits with high inrush currents during startup.
• Motor Circuits: Used in small motor circuits to prevent nuisance tripping due to motor starting currents.
• Transformer Circuits: Protects transformers from overloads and short circuits, while tolerating inrush currents.
• Lighting Ballasts: Provides overcurrent protection for lighting ballasts with inrush current requirements.
• Industrial Control Systems: Used in control panels and industrial equipment where reliable overcurrent protection is essential.

Features:

• Time-Delay Characteristic: Withstands temporary inrush currents without tripping.
• 500mA Current Rating: Designed to handle a maximum continuous current of 500 milliamperes.
• 250V Voltage Rating: Suitable for circuits with a maximum voltage of 250 volts AC or DC.
• Ceramic Body: Provides excellent insulation and high breaking capacity.
• Compact Size: Small form factor allows for easy integration into electronic devices.

Benefits:

• Reduced Nuisance Tripping: Prevents unnecessary circuit interruptions caused by inrush currents.
• Enhanced Equipment Protection: Protects sensitive electronic components from overcurrent conditions.
• Improved System Reliability: Ensures continuous operation of circuits with inrush current requirements.
• Easy Replacement: Standard fuse size and construction allow for easy replacement in the field.
• Cost-Effective Protection: Provides a reliable and affordable solution for overcurrent protection.

Additional Details:
