Short-circuit current calculator

An easy way to calculate prospective short-circuit current levels

The Bussmann series point-to-point short-circuit current calculator is a simple, easy-to-use program that allows you to calculate prospective short-circuit currents with a reasonable degree of accuracy. These values can be calculated on the load side of a transformer, at the end of a run of cable or at the end of a busway. Calculations can be made for single or three phase systems.


I2t Calculator

A quick, easy way to calculate I2t levels

The Bussmann series I2t calculator program allows the user to calculate ampere squared seconds for a given wave forms. I2t is a quantity representing energy which is calculated by finding the area under a given curve. It is given in units of amps squared seconds (A2s). After choosing the correct waveform, the values for the current levels and the time are entered by the user, the program will then calculate the I2t.


Group motor protection guide

A quick and easy-to-use program to help you meet group motor protection requirements

The NEC® section 430.53 allows two or more motors, and other loads, to be protected by the same overcurrent protective device when specific requirements are met. The Bussmann series group motor protection guide program is a quick and easy-to-use program that will tell you if you meet the requirements of group motor protection by asking a series of questions. Once it is determined that you can use group motor protection, you must still meet the group switching requirements of NEC® section 430.112. The group motor protection guide program will ask another series of questions to see if you meet these requirements.


Motor circuit selection guide

A quick, simple way to get the right Bussmann series fuse for a motor application

The Bussmann series motor circuit selection guide program is intended to be a quick and simple way to choose the proper type and size of Bussmann series fuse for a specific motor application. The values from the motor circuit selection guide program are intended only to be guidelines. Because motor inrush characteristics vary, the recommended fuses may not hold the inrush current. Consult our latest catalogs, application literature or contact Application Engineering at 636-527-1270.


Transformer protection guide

Determines the maximum fuse value for a transformer

The Bussmann series transformer protection guide program translates NEC® section 450.3 for overcurrent protection of transformers. Based upon basic information about a transformer, the program will take you through a flow chart to arrive at the maximum fuse value that can be used for your particular transformer.


Fuse selection guide

The easy way to select a fuse

The Bussmann series Fuse Selector Tool is an online application that will help you select a Bussmann series fuse based upon fuse characteristics. The program performs a search based upon electrical or electronic fuse, the voltage rating, AC or DC, time-delay or fast-acting characteristics, and the amp range, fuse class, fuse family, fuse series, fuse body type, size and even application. Any or all of these parameters may be entered to narrow the search results. There is also a version for medium voltage fuses.
