Fuseco can help! We provide a 24 hour 7 day a week service for customers who are experiencing a breakdown situation or need a fuse urgently after-hours or during the weekend.

To use this service, please call our after-hours number 0411 104 363 and one of our customer service team members will be available to assist you. Please note that an after-hours fee applies to this service.

Fuses shall be selected according to the following criteria. 

• Maximum operational voltage – shall be equal or greater than the system operating voltage. 
• Rated breaking capacity – shall be equal to or greater than the maximum fault current expected in the circuit downstream the fuse. 
• Rated current – shall be equal to or greater than the continuous operating current of the circuit protected by the fuse. 
• Breaking range – partial range or full range breaking capacity according to the type of protection required. 
• Utilisation category – select according to the nature of equipment to be protected.

Fuses are in most cases marked with all the essential information required to select a replacement fuse or to enable you to select fuses for most common applications. Additional information, such as performance characteristics can be supplied by the fuse manufacturer. Standard markings are as follows:

• Fuse standard, size and reference. This defines the operating performance and mechanical design of the fuse.
• Voltage rating. Fuses may be operated up to the maximum voltage stated in the rating. Voltage ratings may be colour coded to reduce the risk of incorrect installation.
• Current rating. This represents the value of the current that the fuse can carry continuously with out deterioration under specified conditions.
• Rated breaking capacity. This is the maximum value of prospective current that a fuse is capable of breaking under standard conditions. In other words, the maximum amount of current that a fuse can tolerate without losing its physical integrity (physically breaking apart). Industrial fuses according to IEC 60269-2 have a minimum breaking capacity of A.C. 50kA and D.C 25kA respectively.
• Breaking range and utilization category are indicated by letter codes. The first (lower case) letter indicates the breaking range, i.e. the range of prospective currents the fuse is able to break. The second (capital) letter indicates the utilization category, i.e. time-current characteristics for typical applications.
• Fuse manufacturer or trademark.
• Manufacturer’s product reference or part number, required for additional information on the fuse.

Additional markings may include:

• Rated frequency if other than 50 or 60 Hz. 
• Date of manufacture, useful to trace back product design changes.
• Certification mark, asserting product quality by an independent certification body. 
• Conformity mark, stating conformity to applicable national directives. 
• Recycling mark, identifying responsible recycling organization. 

In most cases, people contact Fuseco when they need to replace an existing fuse that has blown. In such cases, it is paramount that either the identical fuse or an exact equivalent is provided. Care must be taken to make sure that the fuse provided is of the same utilisation category and has the same electrical performance of the original. If you need assistance with this, I welcome you to contact us and we would be very happy to assist you. Also, we provide many types of cross-reference charts on this website, wall charts and various tools that can assist you to identify equivalent fuse types.

Fuses are rated by current, voltage, breaking capacity (interrupt capability) and whether they are designed to operate on AC or DC circuits. The current rating of a fuse is the current that it can carry for indefinite time periods without opening. The voltage rating relates to the ability of the fuse to function and extinguish internal arcs when it opens. The breaking capacity is how large a short-circuit or fault current the fuse can interrupt or stop safely without allowing a continuing arc and without damaging the fuse body or fuse holder.
