Fusetron FRS-R-12 600 VAC Dual Element Time Delay Fuses (Lot of 4)

The Fusetron FRS-R-12 600 VAC Dual Element Time Delay Fuses (Lot of 4) are designed to provide reliable protection in electrical circuits, particularly for applications involving motors, transformers, and other inductive loads. These fuses are built to handle both short-circuit and overload conditions effectively, while also allowing brief surges or inrush currents that are typical during equipment startup.

Here are the key details:

Key Features:

1. 12 Amp Rating:

   • Each fuse in this lot is rated for 12 amps, meaning it will allow current up to 12 amps to flow continuously through the circuit. If the current exceeds this rating for too long, the fuse will blow to protect the system.

2. 600 VAC Rating:

   • The 600 VAC rating means these fuses are designed for use in circuits operating at up to 600 volts AC. This makes them suitable for industrial and commercial applications where high-voltage circuits are in use.

3. Dual Element Construction:

   • These fuses feature a dual-element design: one element protects against short-circuits (blowing quickly to interrupt high current) and the other element offers a time-delay feature for overload protection. The time-delay allows the fuse to withstand brief overloads or inrush currents (such as those found when motors start) without blowing immediately.

4. Time-Delay Feature:

   • The time-delay characteristic means the fuse can tolerate temporary overloads without tripping. This is particularly useful in applications where equipment like motors or compressors experience inrush currents at startup. After a short delay, if the overload persists, the fuse will blow to protect the circuit.

5. Lot of 4 Fuses:

   • This lot includes four fuses, making it a cost-effective option for anyone who needs to replace multiple fuses or maintain several systems requiring 12-amp, 600 VAC protection.

Applications:

• Motors and Compressors: The fuses provide reliable protection against overloads and short circuits, especially in motor-driven applications that experience inrush currents at startup.
• HVAC Systems: They are commonly used in heating, ventilation, and air conditioning systems, where motors and compressors often require time-delay fuses to protect against overloads during startup.
• Industrial and Commercial Equipment: Ideal for protecting circuits in industrial machinery, commercial equipment, and other systems where high-voltage circuits are common.

Benefits:

• Prevents Unnecessary Fuse Blowouts: The time-delay feature helps prevent the fuse from blowing during transient overloads, which could be caused by equipment startup or brief current surges.
• Reliable Protection: The dual-element design provides both fast-acting protection for short circuits and time-delay protection for sustained overloads, ensuring your system remains safe and operational.
• Convenient Lot of 4: Purchasing these fuses in a lot of 4 provides a more economical option for those needing multiple replacements or for equipment maintenance.
