As an example, let us assume that the rated accepted power of a fuse-holder is 2.5 W. Basically, this means that the rated current is not a fixed value. This rated accepted power determines the rated current. For example, it means that at a power dissipation of 4 W (by a fuse link placed in the fuseholder) temperatures of the fuse-holder should not exceed certain limit values as specified in the standard. The rated accepted power is, according to IEC 257, "A stated value of power dissipation (of a fuse link) which a fuse-base or fuse-holder can accept under prescribed conditions of use and behavior." Rated values of accepted power are 1.6 W, 2.5 W or 4 W. According to IEC 257, the rated current is determined by the rated accepted power of a fuse-holder. Considerable differences exist between the IEC and the UL standards regarding the rated current of a fuse-holder. In the following, some of the most important differences between the two standards will be indicated.įrom an application point of view, a fuse-holder is characterized by the features discussed in the previous section by its rated values for voltage, current, and accepted power. In the case of fuse links, compliance with the UL-standard does not usually mean that the fuse-holder under consideration meets IEC-requirements and vice versa. 2 to this publication dated January 1989.īoth standards show considerable differences. IEC-publication 257 (1968) and Amendment no.The most important standards for fuse-holders, which specify requirements, characteristics and testing methods are: How much is available to spend on safety and reliability?.Should the fuse only be accessible from outside the appliance?.Should the end customer of the appliance have access to change the fuse?.How often will the fuse need to be replaced?.Will the fuse need to accessible for replacement?.The first step is to answer the following questions: Items marked with the Dangerous Goods icon below may be subject to shipping/delivery restrictions.Selection of the Fuse and Holder Solution Items that can contain these materials include battery banks, aerosols, some tools and lithium batteries. These include and are not limited to: explosives, radioactive materials, flammable liquids, dangerous or volatile chemicals, strong acids, compressed gases, poisons and aerosols. The majority of our logistics providers deliver to parcel lockers around Australia.ĭangerous goods in reference to shipping are items or substances that when transported are a risk to health, safety, property or the environment. If you don't select insurance you are NOT insured.
We do not automatically insure unless you specify it during the checkout. In other words if your order is for $145.00 the insurance will be $2.00. Insurance will cost $1 for every $100 value or PART THEREOF. This insurance also covers goods DAMAGED in transit. If you do wish to insure, insurance will cost 1% of the order value and we are happy to arrange this on your behalf. Goods cannot be delivered to a post office box.Ĭompany policy is that we do not under any circumstances issue instructions to our couriers to leave deliveries unattended when no one is at the delivery location.įor unusually large or bulky orders our customer service staff may contact you if any additional freight costs are needed. Please contact us should you require more details. Premium freight is not available on oversized/bulky items or in all locations. Please allow extra time for delivery to western states. Additional delivery time may result for some deliveries. ^Freight delivery times stated are for average volume items with total order weight under 5kg for metro areas in eastern states. Freight will be charged at checkout for these items. Standard/Road Freight: 2 - 5 working days^įree delivery exclusions apply to some bulky and large items. Your order can be delivered to anywhere throughout mainland Australia by road freight:
