Ohm The unit of measure for electric resistance.

Bussmann. Circuit Protection Solutions – PDF

JF1, 2 circuits Wire Size: Where trip indicator fuselinks are to be attached to the main fuselink, an accessory pack comprising a pair of mounting clips and an appropriate fusd indicator fuselink will be required.

Minimum of 4 Poles Required. Handle and shaft required for through the door operation.

Two identical half bases make up a Buss Modular fuse base. When replacing the blown fuse, the end fittings should be removed from the operated fuse unit, and if undamaged, clamped onto the new fuse unit. Filetypr only the protective device nearest a faulted circuit opens and larger upstream fuses remain closed, the protective devices are selectively coordinated they discriminate.

Also, it will limit the instantaneous peak let-through current to a value substantially less than that obtainable in the same circuit if that fuse were replaced with a solid conductor of equal impedance.

Your comments or suggestions are welcome and appreciated. Closer protection is offered for many motor sizes with the availability of these additional fuse ratings. If a fault current exceeds the capability of the protective device, the device may actually rupture, causing additional damage. Drawings and general provisions of the Contract, including General and Supplementary Conditions and Divisions 1 Specification sections apply to.

It can be expressed as melting l 2 t, arcing fuletype 2 t or the sum of them as Clearing l 2 t. A simple link element for short-circuits and dangerous overloads plus a series-connected element which lets the harmless overload starting currents of motors pass without opening.

Page Product Description and Definitions They can either be attached to the associated fuselink or mounted separately in panel mounted fuse clips, Part No.

Fuse characteristics are stable. When a fuse is subjected to a current above its ampere rating, it will open the circuit after a predetermined period of time. DO NOT test electrical fuses in the fuse panel. BBU Fuse Construction The components are housed in a fiberglass reinforced resin tube with plated copper contacts.

They restrict fault currents to such low values that a high degree of protection is given to circuit components against even very high short-circuit currents. The arching rod is prevented from falling back into its original position by a friction stop at the top of the fuse unit. See Data Sheet for dimensional drawings.

Semkconductor cable and fuse connections are similar to the Stud Type fuse base both are mounted on the same stud. Bipolar alarm designed for both Central Office and Radio applications. Clearing time is the total of the melting time and the arcing time. All you need is a touchtone telephone and a fax machine to get complete product specifications when you want it.

Buss Yellow light on indicating SAMI shows when the fuse is open helps trouble shoot the system and reduces downtime. A fusible link or links encapsulated in a tube and connected to contact terminals comprise the fundamental elements of the basic fuse.

Under normal operation, when the fuse is operating at or near its ampere rating, it simply functions as a conductor. Blocks are molded flame retarded thermoplastic. Under sustained overload, a section of the link melts and an arc is established. Interrupting rating ofamperes complies with NEC Sections and for today s large capacity systems. JN, 12 circuits Wire Size: Now Available in 1 Position.

No End Barrier Only. Your business or home from More information. Bussmann Semkconductor only page Compact branch-circuit units with high bussmajn rating and current limitation.

Tin-plated Beryllium copper Carton Qty. Options For Load Side Connector: Alarm output with wire wrap terminal or connection to. Single-pole and 2-pole fuse blocks 1,; Multiple-pole fuse blocks pole: An ampere is the amount of current that will flow through a resistance of one ohm under a pressure of one volt.

These fuses are current-limiting.

Indicator fuses can be attached to the associated fuselink, or mounted separately in panel-mounted fuseclips. Fuse assortment same as the x 10 The ampere rating of a fuse normally semiconductod not exceed the current carrying capacity of the circuit. Number 1,3R,12 IP65 Black 4.

Circuit board applications available.

NH HRC Fuses

End Piece Part No. High temperature, flame retardant, thermoplastic; UL Component Recognized; 94VO; mounting nut, spacer-black polycarbonate. Accessories Ferrule fuses may be mounted in fuse clips, fuseholders, fuseblocks or fused switches.
