What size is a class CC fuse?
Very compact, with a physical size only 13⁄32″ x 11⁄2″ (10.3 x 38.1mm) with rejction tip. Proper sizing can provide “no damage” Type 2 coordinated protection for NEMA and IEC motor controllers.
What is class fuse?
A Class T fuse is a fast acting, current limiting, fuse that is rated to interrupt a minimum of 200,000 amps. The Type T Fuse is offered in 300 volt AC and 600 volt AC versions. Type T Fuse ampere ratings range from1 to 800 amps.
What is Class G fuse?
What is a Class G, Fuse? A UL Class G fuse is a 600/480 volts AC current limiting, fuse that is rated to interrupt a minimum of 100,000 amps. Ampere ratings range from ½ amp to 60 amps. The type G fuse meets the NEC, requirements for branch circuit, protection.
What are Class CC fuses used for?
Class CC fuses. These non-renewable fuses are current-limiting and intended for the protection of components sensitive to short-time overloads, non-inductive loads, and short-circuit protection of motor circuits. Current ratings range from 0A to 30A, and the voltage rating is 600VAC.
What does CC mean in fuses?
Class CC fuses are current limiting fuses with rejection tips on the bottoms to prevent them from being used in holders not rated similarly. A Current-Limiting Fuse meets the following three conditions: Interrupts all available overcurrents within its interrupt rating.
What is the difference between a Class J and Class R fuse?
Class R fuses are available with DC ratings. They have an interrupting rating of 200kA rms symmetrical and are separated into two separate classes, RK1 and RK5. Current ratings of UL Class J fuses range from 0A to 600A, and the voltage rating is 600VAC. Class J fuses are available with DC ratings.
What is the difference between A Class J and Class R fuse?
What is a Class SC fuse?
SC-(amp) Description: Basic protection Class G size-rejecting, current limiting fuses. 1/2 to 6A Fast-acting, 7 to 60A time-delay. Time-delay – 12 seconds (minimum) at 200% of rated current.
What is a class R fuse?
Class R (“R” for rejection) fuses are high performance, 1⁄10 to 600A units, 250V and 600V, having a high degree of current-limitation and a short-circuit interrupting rating of up to 300,000A (RMS symmetrical). NEC® 110.9 requires that protective devices have adequate capacity to interrupt short-circuit currents.
What is class CC fuse holder?
A UL Class CC fuse is 600 volt AC current limiting, rejection type fuse. The Class CC fuse is the smallest 600 volt, 200,000 A.I.R. fuse approved for branch circuit, protection.
How do you calculate fuse rating?
The fuse rating can be calculated by dividing the power used by the appliance by the voltage going into the appliance. I (Amps) = P (Watts) ÷ V (Voltage). A fuse for a machine is rated on the load that the machine carries when running.
What is E rated fuse?
An E-Rated fuse provides transformer protection and is a current limiting general purpose power fuse that provides overload and short circuit protection. They are designed to withstand the large magnetizing inrush that occurs during transformer start-up.
What are the different types of electrical fuses?
Types of Electrical Fuses. Most fuses can be split into two main categories – AC & DC fuses. Besides their size differences, AC fuses (alternating current) allows for the reverse flow of currents, and are relatively simple by design. A DC fuse (direct current) are little more complex in design, and are made for currents to pass in a single direction.
What size are automotive fuses?
Standard fuse sizes range from ¼” diameter, 5/8” length (1AG) to ¼” diameter 1” length (8AG), to 5mm x 20 mm, pico fuses and automotive blade. “Automobile Glass” fuses use the term “AG” in the fuse size designation.
