Littelfuse KLDR Series Time-Delay Fuse — 7 A, 600 V AC, Non-Indicating

Key Features:

• Series: KLDR — Class CC fuse family with time-delay design ideal for protecting industrial control circuits and inductive loads.  
• Amperage: 7 A continuous rating.  
• Voltage: Rated for up to 600 V AC (also 300 V DC).  
• Speed: Time-delay (slow-blow) — allows short inrush currents (typical with motors/transformers) without nuisance blowing.  
• Indication: Non-indicating — fuse does not include a blown indicator.  
• Interrupt Rating: Very high fault clearing capability — 200 kA at 600 V AC and 20 kA at 300 V DC.  
• Body: Cylindrical, melamine construction for durability and UL/CSA approval.  
• Size: 13/32 in diameter × 1 1/2 in length — fits standard Class CC holders with rejection style.  
• Approvals: UL Listed, CSA Certified, RoHS compliant.  

What it’s used for:

This fuse is designed for short-circuit and overload protection in control circuits, general branch circuits, and equipment with inductive components (like control transformers or solenoids). Its time-delay characteristic lets equipment start up without blowing the fuse during normal inrush current. 

Benefits:

✔ Protects electrical systems from surge and fault conditions

✔ Time delay reduces nuisance interruptions on inductive loads

✔ High interrupting capacity improves safety in industrial environments
