Amprobe Test Tools has been a leading manufacturer since the late 1940s, when it introduced its first patented product, the Clamp-on Ammeter. Over the past 60 years, the Amprobe brand has become closely associated with clamp-on meters and has significantly broadened its product range to include over 250 items. As a result, Amprobe has established itself as a premier provider of high-quality test equipment for professionals working in the electrical, maintenance, construction, and HVAC sectors. Today, Amprobe is the preferred choice for professionals seeking feature-rich products, such as clamp-on ammeters, a comprehensive range of multimeters, HVAC measurement tools, power quality analyzers, electrical testers, and wire/circuit tracers. Moreover, Amprobe has expanded its expertise to specialize in Power Quality (PQ) equipment, offering a diverse selection of advanced tools for field measurement and recording of PQ variables, including power, energy, harmonics, spikes, sags, and surges.
Circuit protection, specifically specialty fuses in the electrical domain, refers to a range of products designed to safeguard electrical circuits from over-current faults. These specialty fuses are distinct from standard fuses and serve as primary circuit protection devices. They are engineered to respond to excessive current flow by triggering the destruction of a conductive element within the device, effectively interrupting the circuit and preventing damage to connected components. One key characteristic of specialty fuses is their classification under the UL248 standard as non-supplementary, emphasizing their primary role in safeguarding main circuits. Additionally, certain specialty fuses are certified for use in hazardous or explosive environments, meeting stringent safety requirements to mitigate ignition or explosion risks. These fuses exhibit form factors that differentiate them from those commonly used for supplementary equipment protection, such as fuses with indication functions or fusible cable links. Furthermore, specialized versions cater to specific applications, including the protection of telecommunications circuits or multimeters. The proper selection and utilization of these circuit protection accessories are crucial in ensuring the safety and reliability of electrical systems. Adherence to relevant safety standards and guidelines is essential for the correct installation and maintenance of these devices, which play a critical role in preventing over-current faults and supporting the secure operation of diverse applications.
