Note that at the 1,A overload level, the time interval which is required for the fuse to open is 10 seconds. The tilt bins are available in five and six bin models.

NH HRC Fuses

Element is a simple fusible, metal link. Single-element fuwe of present day design have a very high speed of response to overcurrents. ClassFile Indication: Low energy let-thru I 2 t Low watts loss Superior cycling capability Low arc voltage Excellent dc performance North American style fuses provide an excellent solution for medium power applications.

Once a product has been selected, it should be tested by the user in all possible applications Cooper Bussmann Printed in the U. Bright Tin Data Sheet: 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.


Complete semuconductor coordination capability.

NH HRC, Fuses, Fuse links

Single pole blocks may be ordered without the antirotational pin simply by adding an X to the number of poles Example: The operating voltage of the indicator is 1. Carton Quantity and Weight Ampere Carton.

Full Range – defined by ANSI as a fuse capable of interrupting all currents from the maximum rated interrupting current down to the minimum continuous current that causes melting of catakogue fusible element swhen the fuse is applied at the maximum ambient temperature specified by the manufacturer. Cutaway view of typical single-element fuse. Amps Surge Fast Slow Lbs.

Fuse Display Merchandiser will consist of any number of either size bins; header card push pegs to attach filetyype part number labels. RK1 and RK5 fuses fit standard switches, fuseblocks and holders; however, the rejection feature of class R switches and fuseblocks designed specifically for rejection type fuses RK1 and RK5 prevent the insertion of the non-rejection fuses K1, K5, and H.

The open single-element fuse after opening a short circuit. This condition results in unbalanced currents in polyphase motors and unless protective measures are taken, causes overheating and failure.

Semiconcuctor products include the most extensive circuit protection solutions approved for use in a variety of major standards: High speed of response semiconducyor highly sensitive to fault currents, but insensitive to starting current and transient surges.


Siemens Sentron molded case circuit More information. Clearly defined performance characteristics Based. Short Circuit Can be classified as an overcurrent which exceeds the normal full load current of a circuit by a factor many times tens, hundreds or thousands greater.

The minimum voltage for operating the indicator is 20V. Sturdy storage cabinet conveniently holds spare fuses. Consult fixture manufacturer for size and type. Dead front construction provides added protection against accidental contact by maintenance personnel.

They are fast acting and time-lag fuses, with an interrupting rating of ,A RMS. Time-delay 13 capacitor banks A time-delay passes surge currents.

Bussmann. Circuit Protection Solutions

When subjected to a short-circuit current, several sections of the fuse link melt almost instantly. Tin plated copper alloy Contact Lubricant: Stainless steel Optional Accessories: Innovative new fuse pullout design eliminates need for tools to replace the Telpower type TPL-B fuse.
