Fusetron FRS-R-5-5/10 Dual Element Time Delay Fuse (Lot of 5)

The Fusetron FRS-R-5-5/10 Dual Element Time Delay Fuse is commonly used for the protection of electrical circuits, particularly in situations where the equipment is subject to inrush currents, such as electric motors, compressors, and other inductive loads.

Key Features:

1. Dual Element Design:

   • The fuse has two elements: one for protecting against short circuits (fast-acting) and the other for handling overload conditions (time-delay).
   • This design allows the fuse to absorb temporary inrush currents without blowing unnecessarily.

2. Time Delay Function:

   • The time-delay characteristic allows the fuse to withstand brief overloads, which are common at startup in motors or equipment with a high initial current. This delay ensures that the fuse only blows if the overload persists for longer than the set time (typically around 5-10 seconds, hence the 5/10 rating).

3. 5 Amp Rating:

   • The fuse has a nominal current rating of 5 amps. It is crucial to match this rating with the current requirements of your circuit to ensure proper protection.

4. Voltage Rating:

   • Typically, the FRS-R series fuses are rated for use at 250 volts AC. You should check your circuit voltage to ensure compatibility.

5. Interrupting Rating:

   • These fuses are designed with a high interrupting rating, meaning they can safely interrupt the flow of current if a short circuit or fault occurs, without damaging the fuse or posing a safety hazard.

6. Lot of 5:

   • The “Lot of 5” indicates that you are purchasing five individual fuses, which is convenient if you need multiple replacements or if you’re maintaining multiple pieces of equipment.

Applications:

• Motors and Transformers: The time-delay feature helps protect motors from damage due to inrush currents during startup.
• Industrial and Commercial Equipment: Ideal for protecting circuits with inductive loads where brief surges of current may occur.
• HVAC Systems: Often used in air conditioning and heating systems for overload protection.

Overall Benefits:

• The Fusetron FRS-R-5-5/10 fuse helps improve the longevity and safety of electrical systems by protecting sensitive components from overloads and short circuits, while preventing unnecessary fuse blowouts due to temporary surges.
