RS0 and RS3 series filled fast-acting fuses are suitable for AC 50Hz, voltage 750V and below, rated current 30 to 600A, mainly used for silicon rectifiers and thyristors and their complete sets of short circuit or overload protection.
The document explains the intended use of the RS0 and RS3 series filler quick fuses, which are designed for AC 50 Hz systems with voltages up to 750 V and rated currents from 30 A to 600 A. It also lists the applicable standards and typical applications such as protection of silicon rectifiers and thyristor assemblies.
Technical details cover normal operating conditions (altitude, temperature, humidity), construction features, model designation, key electrical parameters, protection characteristic curves, and mechanical dimensions required for proper installation. This manual is written in Chinese.

They are suitable for AC 50 Hz systems with voltage up to 750 V and rated current from 30 A to 600 A.
Creepage must be at least 12 mm and electrical clearance at least 8 mm.
Quartz sand is used as filler to cool the arc and quickly extinguish it.
