The RS2-12-C3 is a Class CC time-delay fuse manufactured by Eaton Bussmann. It is designed to provide overcurrent protection for control transformers, solenoids, and other inductive loads. The time-delay characteristic allows for brief inrush currents without nuisance tripping, while still providing reliable protection against sustained overloads and short circuits.

Applications

• Control transformers.
• Solenoids.
• Motor control circuits.
• Lighting circuits.
• General-purpose circuit protection.

Features

• Class CC fuse: Provides high interrupting capacity and current limitation.
• Time-delay characteristic: Allows for temporary overloads without tripping.
• 12 Amps rating: Suitable for circuits with a maximum current of 12 Amps.
• 250 Volts AC rating: Designed for use in circuits with a maximum voltage of 250 Volts AC.
• Rejection feature: Prevents the insertion of fuses with lower interrupting ratings.

Benefits

• Reliable Overcurrent Protection: Provides dependable protection against overloads and short circuits.
• Nuisance Tripping Reduction: Time-delay characteristic minimizes nuisance tripping caused by temporary overloads.
• High Interrupting Capacity: Safely interrupts high fault currents.
• Current Limitation: Reduces the magnitude of fault currents, minimizing equipment damage.
• Safe Operation: Rejection feature prevents the use of incorrect fuses, ensuring safe operation.

Additional Details

The RS2-12-C3 fuse is designed to meet the requirements of Class CC fuses, which are known for their high interrupting capacity and current limitation capabilities. The time-delay characteristic allows for brief overloads, such as those that occur when starting a motor or energizing a transformer, without causing the fuse to blow. The 12 amp rating indicates the maximum continuous current that the fuse can carry without tripping. The 250 volt AC rating indicates the maximum voltage that the fuse can safely handle. The rejection feature prevents the use of fuses with lower interrupting ratings, ensuring that the circuit is properly protected. This fuse is commonly used in industrial and commercial applications where reliable overcurrent protection is essential. The interrupting rating is typically 200,000 amps.
