ERB-RD3R00X Circuit Protection

Fuses are components used in electrical circuits to protect electrical devices from major damage due to overcurrent and overvoltage. The ERB-RD3R00X is one such fuse with unique properties and specialized application fields which makes it particularly useful in certain sectors.

Specifically speaking, the ERB-RD3R00X is a highly reliable 155A (maximum interrupting current) ceramic riveted hold current fuse. Its operating temperature range is usually between -40 to 80 degree Celsius, whilst its melting time index range is between 0.4 and 0.5 seconds. The ERB-RD3R00X is a large current fuse with superior stability characteristics and the electrical endurance is up to 25 times its rated current.

The major application fields of the ERB-RD3R00Xare mainly in outdoor electrical appliances such as transformers, insulator banks, switchboards, gas-insulated switchgear, micro-grids, and many other industrial electric systems. In particular, the ERB-RD3R00X has been used widely in distribution systems due its enhanced features such as long-term electrical life and mechanical strength. As its arc voltage is particularly low, the ERB-RD3R00X can decrease switching electric spark, vastly improve busbar anti-flash capability and reduce the busbar leakage.

The working principle of the ERB-RD3R00X is relatively simple and is mainly dependent upon the heating effect of the current. When a current of over-limit flows through the ERB-RD3R00X, the heat generated will be able to heat up the melting element inside the fuse to melt it and thus create an openings in the circuit, breaking the current. This will stop a major current flow damaging the electrical device connected to the circuit and make the work environment safer.

All in all, the ERB-RD3R00X is an extremely beneficial fuse in many sectors and its high stability, current withstandance, mechanical strength and long-term electrical life makes it an ideal choice for many sectors such as transformers, insulator banks, switchboards, gas-insulated switchgear and micro-grids. As such, the ERB-RD3R00X is an incredibly important component in many electrical devices.
