    Abstract: Disclosed is a fuse resistor provided on an electrical circuit to protect the electrical circuit and elements. The fuse resistor includes a substrate on which first and second resistive terminals and fuse terminals are formed, first and second resistive elements surface-mounted on the first and second resistive terminals and dividing applied current or voltage, and a temperature fuse surface-mounted on the fuse terminals and broken by heat generated from the first and second resistive elements. If overcurrent or overvoltage is applied, the first and second resistive elements generate heat and the temperature fuse is broken by the generated heat.

    Abstract: A bus bar assembly and current measuring device configured to reduce measurement errors through linearity compensation and temperature compensation for the difference in values of two or more measured currents, thereby achieving high-accuracy current measurement, is presented. The present invention discloses a bus bar assembly including: a first conductive plate and a second conductive plate each composed of a plurality of parts; and an insulator formed between the first conductive plate and the second conductive plate, wherein a common first terminal hole is formed at one end of the first conductive plate, one end of the second conductive plate, and one end of the insulator, a common second terminal hole is formed at respective opposite ends of the first conductive plate, the second conductive plate, and the insulator. According to the present invention, stable and highly reliable current measurement is possible through multiple shunt resistors based on a redundancy design.
