Use these fuse charts to find the best fuse type given your required fuse overload characteristics, interrupting rating amps, AC voltage rating, and available amps fuse rating. Select a UL fuse class to see fuse characteristics and vendor information for that UL class of fuses.

Fuse size not to exceed 125% of transformer secondary rated amps. RECOMMENDED . FUSES: LENRK, ECNR, NCLR, JDL or LCU. *Fuse size must not exceed ampacity of conductors. Where selectivity is desired, . Determine non-continuous motor load (N.E.C. 430-22a EX. Add to “a)” above. Determine A/C or refrigeration load.

2018年7月6日 · Find the items that you’re installing and their current requirements. Add the values and divide by 1000 to get your total current in Amps. You can use this value in the fuse size chart above to determine the minimum wire size required.

Determine the ampacity (current-carrying capacity) of the smallest wire on the circuit (you can use the table below which lists allowable amperage for conductors based on AWG size, temperature rating, and whether inside or outside of an engine space).

To find wattage, you multiply amperage by voltage. Example: To find the maximum wattage that a 14 gauge wire circuit can safely accommodate: 15 amps x 120 volts = 1800 watts. A correctly fused circuit will not overheat if an overload occurs; the fuse will "blow," or …

CURRENT RATING: The nominal amperage value of the fuse. It is established by the manufacturer as a value of current which the fuse can carry, based on a controlled set of test conditions (See RERATING section). Catalog Fuse part numbers include series identification and amperage ratings. Refer to the FUSE SELECTION

The variety of Weidmuller terminal block product lines provides the engineer with a broad list of options for fuse selection. Smaller fuses such as the 5x20mm and 1/4" x 1-1/4" are easy to insert into the hinged top style of fuse blocks.

2023年6月17日 · Here is a chart showing common ampere (A) fuse sizes: These maximum ampere ratings are approximate and can vary depending on the specific fuse model and manufacturer. It's important to consult the manufacturer's documentation or electrical code guidelines to determine the appropriate fuse size and ampere rating for your specific application.

2021年9月30日 · To choose the appropriate fuse amp erage, you must first determine the circuit's full-load steady-state current at a temperature of 25° C (68° F). Once the current value has been determined, a fuse rating of 135% of the current value should be chosen (taken to the next standard value).
