   √ Rated voltage: 500/690V or 400V.
   √ Rated current: Up to 1250A.
   √ Provides overload and short-circuit protection (gG/gL rating).
   √ Specialized protection functions:Semiconductor devices and complete equipment installations (aR/gR/gs/gtr ratings).
   √ Motor short-circuit protection (aM rating).
   √ Compliant with:National standard: GB13539.
                              International standard: IEC60269.

2. Product Composition
   √ Consists of two key components:Fuse Link: Core current-interrupting element.
   √ Fuse Base: Mounting and connection base.

3. Fuse Base Features
   √ Material: High-strength ceramic or high-temperature resin construction.
   √ Contact Design: Wedge-type static contacts for secure electrical connection.
   √ Structural Advantages:Open design for superior heat dissipation.
   √ High mechanical strength and operational reliability.
   √ User-friendly installation and maintenance.
   √ Tool Compatibility: Supplied with an NH fuse puller for safe removal.

4. Fuse Link Design
   √ Sealing: Enclosed in a short tube made of high-strength porcelain for environmental protection.
   √ Conductor Material: Pure copper or silver strips (or silver wire) for optimal conductivity and melting characteristics.

5. Arc-Quenching Mechanism
   √ Filling Medium: Chemically treated high-purity quartz sand inside the fuse tube.
   √ Function: Rapidly extinguishes arcs generated during fault current interruption.

6. Protection and Signaling Features
   √ Visual Indicator: Optional built-in indicator for immediate visual identification of blown fuses.
   √ Striker Mechanism: Triggers mechanical signals (e.g., alarm contacts) to activate external warning systems or control circuits.
   √ Automatic Transfer Circuit Integration: Supports integration into pilot devices for automatic power transfer or backup system activation.
