HVJ-1-1/2 fuses are comprised of rectangular-shaped non-indicating fuses that are the everyday choicewhen it comes to circuit protection. These fuses work to limit overload and short-circuit currents in low and medium voltageelectrical circuits. The popular and reliable HVJ-1-1/2 interrupts current in the event of an overcurrent or short-circuitfault. The fuses have also been proven to be capable of isolating and breaking parallel circuits with unlimited current. Withsuch impressive capabilities, HVJ-1-1/2 are widely used in nuclear, industrial, commercial, and residential applications.

HVJ-1-1/2 have impressive environmental resilience and a maximum continuous current rating of 200 RMS amps at 600volts. These fuses operate safely and reliably in ambient temperatures ranging from -30°Celcius to 600°Celcius. Thesuitable applications environment may vary from dry locations to wet locations, as well as safely arcing positions. They arerated for 0-25 percent rated voltage. HVJ-1-1/2 also have overpressure protection capabilities which helps to reduce the riskof shock hazards.

Principally, the working principle of HVJ-1-1/2 fuses relies on the temperature of the conductor in which the fuse is interposed.At normal currents, the heat generated by the transmission of power is low. However, in case of an overload or short-circuit,the temperature of the conductor increases proportionally. That is when the fusesaction becomes important.

When an overload or short circuit occurs, the conductor’s temperature increases significantly beyond the fuses setpoint value.The increased temperature melts and vaporizes the fuse link, abruptly interrupting the flow of current through the circuit. Theinterruption of current prevents any damage or overheating of components in the circuit, limiting any hazardous conditions. Assoon as the fault is resolved, the fusesneed to be replaced.

Overall, HVJ-1-1/2 are ideal for all sorts of electrical applications as these fuses provide reliable circuit protection whileensuring safety. With a broad selection in stock, customers can always find the perfect fuse for any specific application.
