The International Electrotechnical Commision (IEC) Standard for through hole and surface mount fuses. Offers space saving advantages over typical Class J fuses. This means that the CE symbol is not a quality or standard conformity approval, but an administrative sym, The CE Mark is a mandatory conformity mark for products or components placed on the market in the European Economic Area (EEA). E-rated medium voltage fuses are general purpose fuses that are primarily used to protect transformers and provide both cur. This type of fuse is not designed to withstand temporary overload currents associated with some electrical loads. The Clip Lock design provides a reliable, high-pressure contact. Modified Reset (Type II) refers to the Modified Reset mechanism in a thermal circuit breaker. The Underwriter Laboratories (UL) standard for Class H non-renewable power fuses. How to Recharge a Dead Car Battery Safely and Quickly. Two or more circuit breakers in a single package that are electrically isolated but mechanically tied. A reed is a basic component of a reed switch. The primary use is to protect solid state electronic components.Their special characteristics, including quick overload response, v. A 32 volt DC fuse designed for the telecom industry. Maximum voltage which can be measured across the protector when subjected to the Maximum Peak Pulse Current based on 10/1000µs exponential waveform. An industry standard radial leaded package where the device body is 4.98mm in length by 4.73mm in width (max). This means your cooling fans will still work if they experience a brief high-draw issue, without have to replace the fuse. Recommended for use on DC circuits. The International Standard for IEC style High voltage current limiting fuses with Voltage Ratings from 3.6kV to 36kV. These are available in ratings from 1A through 60A. A two color circuit breaker rocker actuator that offers front panel operation and visual indication of the ON or TRIPPED/OFF mode. A potential of one volt appears across a resistance of one ohm when a current of one ampere flows through that resistance. Littelfuse brand name for a specific fuse designed for use on the terminals of automotive style batteries. Varistor AC power dissipation measured at rated RMS voltage Vm(ac). There are a select few instances where you can go up to a larger fuse, but only when you absolutely know that the wiring is capable of handling the extra current. A 600 volt AC, 600 volt DC fuse designed specifically for the protection of photovoltaic (PV) systems. A marine standard for ignition protection. This article will address and identify the most common types of automotive fuses that you may encounter. A switch that automatically returns to its original or at rest position. Littelfuse brand name for a surge resistant time delay surface mount fuse designed specifically for the telecommunications industry (Series 461). Bussmann brand name for a surge resistant time delay surface mount fuse designed specifically for the telecommunications industry . Exceeding the voltage rating of a fuse impairs its ability to clear an overload or short circuit safely. An industry standard surface mount package that is 10.67mm in length by 10.54mm in width (max). Mersen CL-14 fuses have copper tabs which slide into position between the clip casting and cam. Also referred to as a renewable element. Non-isolated mounting tab. The SAE Standard for Modified Reset Circuit Breakers. Maximum recurrent peak voltage which may be applied for a specified duty cycle and waveform. The part of a switch assembly that causes the switch contacts to engage or disengage. Total measure of thermal energy developed within a circuit during the fuse’s clearing of a fault current. A switch that is isolated electrically from the circuit breakers circuit. An industry standard radial leaded package where the device body is 4.98mm in length by 4.73mm in width (max). Ampere is often abbreviated as “A”. © Copyright National Automotive Parts Association. Littelfuse brand name for a lower profile type of mini automotive blade fuses. International Shock Safe fuseholders are designed to eliminate the possibility of electrical shock. The Circuit Protection Specialist800-255-1919To Place International Orders Please Call: 440-238-1330, To Place International Orders Please Call: 440-238-1330. MOV's are constructed with a zinc oxide disc, m, A voltage sensitive surface mount device designed to protect circuits from transient voltage surges generated from Electrostatic Discharge (ESD), inductive load switching or lightning surge remnants. UC/CSA/NOM standards are followed. RoHS stands for Reduction of Hazardous Substances. This symbol is applied to Universal Modular Fuses (UMF) that has been found to be compliant with IEC 60127-4. The maximum voltage at which a fuse is designed to operate. The circuit breaker is reset by pushing the knob in. It is measured at a DC test current listed on the datasheet (typically 1mA). The volt (V) is the Standard International (SI) unit of electric potential or electromotive force. The fuse voltage drop or difference across its terminals when measured using a test current of 100% of the fuse's nominal rated current. Littelfuse brand name for a larger automotive blade style fuse designed to carry higher currents. Replacing a bad fuse is fairly easy in most cases, but you do need to take a few precautions. Since UL is accredited by the Standards Council of Canada as a Certified Organization and Testing Organization, it can perform component testing to applicable Canadian standards.
