| Brand | Littelfuse |
| Model Number | KLDR-1-6/10 |
| Manufacturer Catalog Number | KLDR01.6 |
| Product Marking | KLDR 1 6/10A |
| Product Category | Class CC Time-Delay Fuse |
| Product Series | POWR-GARD KLDR |
| Current Rating | 1.6 A (1600 mA, 1-6/10 A) |
| AC Voltage Rating | 600 VAC |
| DC Voltage Rating | 300 VDC |
| Fuse Class | UL Class CC |
| Operating Characteristic | Time-Delay |
The Littelfuse KLDR-1-6/10 provides a 1.6 ampere current rating for appropriately specified industrial control circuits, control transformers and inductive equipment. Its 1600 mA rating supports applications requiring Class CC time-delay overcurrent protection.
Rated for compatible AC circuits up to 600 VAC and DC circuits up to 300 VDC. Separate AC and DC interrupting ratings allow electrical protection selection according to the circuit voltage and available prospective fault current.
The time-delay characteristic accommodates temporary magnetizing inrush currents associated with energizing control transformers, solenoids and similar inductive components. Manufacturer documentation specifies a minimum opening time of 12 seconds at 200% of rated current under the applicable UL requirement.
Provides a 200 kA RMS symmetrical interrupting rating at 600 VAC and a separate 20 kA interrupting rating at 300 VDC. Littelfuse identifies the DC interrupting rating as self-certified. Both ratings must be evaluated against the available short-circuit current.
The current-limiting construction helps reduce heating and magnetic effects during short-circuit conditions. Its rejection capability helps prevent the installation of unsuitable fuses with lower voltage or interrupting ratings when used with compatible rejection-style fuse holders.
Features a melamine body, nickel-plated bronze end caps and a nominal 10.3 x 38.1 mm cartridge format. Compatible mounting options include appropriately rated Littelfuse L60030C, LPSC/LFPSC, LEC and 571/572 fuse holder series.
We support online purchase of the Littelfuse KLDR-1-6/10 Class CC Time-Delay Fuse. If you need to make bulk purchases and inquire about other products, please contact our team to inform us of your purchase requirements. We will provide you with information such as quantity quotations, delivery dates, and transportation methods. Please verify the required model, current rating and purchase quantity before ordering.
What is the Littelfuse KLDR-1-6/10?
It is a 1.6 A Class CC time-delay, current-limiting cartridge fuse from the Littelfuse POWR-GARD KLDR series. The fuse is intended for compatible control transformer, solenoid and industrial control applications.
What is the manufacturer catalog number?
The corresponding Littelfuse catalog number is KLDR01.6. The manufacturer identifies its product marking as KLDR 1 6/10A.
What is the current rating?
The current rating is 1.6 amperes, equivalent to 1600 milliamperes or one and six-tenths amperes.
What are its AC and DC voltage ratings?
The manufacturer specifies 600 VAC and 300 VDC. The circuit operating voltage must not exceed the applicable rating.
What are the interrupting ratings?
The AC interrupting rating is 200,000 amperes RMS symmetrical at 600 VAC. The DC interrupting rating is 20,000 amperes at 300 VDC and is self-certified by Littelfuse.
Is KLDR-1-6/10 a time-delay fuse?
Yes. The KLDR series is designed to tolerate brief magnetizing inrush currents when energizing control transformers, solenoids and comparable inductive loads.
Does it open in exactly 12 seconds at twice the rated current?
No. The applicable UL requirement specifies a minimum opening time of 12 seconds at 200% of rated current. This is not a fixed opening time. Consult Littelfuse time-current curves for circuit protection analysis.
What are the pre-arcing and total clearing I²t values?
Littelfuse lists a pre-arcing I²t value of 0.7495 A²s and a total clearing I²t value of 6.682 A²s. The total clearing value is specified in the manufacturer's 200 kA test-condition column.
What are the nominal physical dimensions?
The fuse has a nominal diameter of 10.3 mm and a nominal length of 38.1 mm, approximately 0.41 x 1.50 inches.
What materials and fuse holders are used?
The KLDR series uses a melamine body with nickel-plated bronze caps. Littelfuse recommends compatible holders from the L60030C, LPSC/LFPSC, LEC and 571/572 families. The exact holder must meet the electrical and mechanical requirements of the installation.
Is KLDR-1-6/10 UL listed and RoHS compliant?
Littelfuse identifies the KLDR series as UL Listed under file E81895, CSA Certified under file LR29862 and RoHS compliant. Its datasheet also references a CE declaration. The DC interrupting rating is manufacturer self-certified.
What should be verified before ordering KLDR-1-6/10?
Confirm the KLDR-1-6/10 or KLDR01.6 model designation, 1.6 A current rating, 600 VAC or 300 VDC circuit requirement, applicable interrupting capacity, time-delay behavior, compatible Class CC holder and offered quantity. Manufacturer ordering numbers KLDR01.6TXP and KLDR01.6HXP refer to 10-piece and 100-piece packaging, respectively, and do not establish the quantity supplied by an individual store listing.
