Fuses Made Simple™- Control Circuits

The easiest and fastest way to select and specify the right control circuit fuse

Bussmann’s Fuses Made Simple program provides the easiest and fastest way to select and specify the right fuse. Whether it’s branch circuit or control circuit (supplemental) fuses, we take the guesswork out of selecting the right fuse. What’s more, we make it simple to replace fuses with six color groups (categorized by voltage rating)--all while enhancing the safety of the electrical system.

Find the control circuit fuse you need in three simple steps:

1. Type

Select the fuse type. Select from time-delay (for inductive loads) or fast-acting (for resistive loads).

2. Voltage

Select the voltage rating needed. Keep in mind that fuse voltage rating must be equal to or greater than the circuit voltage.

3. Interrupting Rating

Verify that the interrupting rating of the fuse selected is sufficient for the circuit application. Keep in mind that the interrupting rating must be equal to or greater than the available short-circuit current.

Three Tiers

Three tiers of protection offer distinct levels of performance benefits to help you speed up specification and selection.

Ultimate Protection – The best worry free protection in virtually any application. Unique dual-element construction delivers a powerful combination of all performance options in one fuse - fast short-circuit protection, current limitation, and time-delay performance with up to 300kA interrupting ratings.

Advanced Protection – Application specific protection for sensitive devices and critical components or motors and transformers. Choose between fast short-circuit, current limiting performance or energy efficient, current limiting, time-delay performance based on the application. Featuring 200kA interrupting ratings.

Basic Protection – Basic single-element protection for service, feeder and branch circuit applications. Featuring up to 100kA interrupting ratings.

Four Families - Each with Unique Color-Coded Labels

Inside these three protection tiers are four distinct families - Low-Peak, FUSETRON, Limitron and General Purpose - each represented by a unique color for their key protection and performance benefits.

Product Profile # 10117

* Test results are based on weighted sales volume of FUSETRON and Ferraz Shawmut (Mersen) fuses by selected amp and volt rating combination. Next leading brand refers to Ferraz Shawmut based on third-party fuse market share data for a twenty-seven month period (July 2008 through September 2010).

Black Label Limitron Fuses - Advanced Critical Component Protection

• 10X Better current limitation than basic circuit breakers or fuses* to help prevent equipment
damage caused by short-circuit events

• Ideal for critical industrial or commercial applications that have specific current limitation
requirements

• Broad fuse family including Class CC, J, L, R, and T with 200kA interrupting ratings

• Most common fuses in stock and ship within 24 hours with QuikShip Everyday Service

Product Profile # 10118

* Does not include current limiting circuit breakers or current limiting fuses. Protection determined by comparing published values for let–through for Class CC, J, R, and T fuses versus a symmetrical RMS waveform at 200kA.
