HBC FUSE LINKS OFF SET TAGS [SURDHI]

Surdhi (Super Engineering Works), the "Two-Hole Fixing" refers to their Bolted Type HBC Fuse Links, specifically the SDV-TSA or SDV-TIS series. These fuses are designed with offset tags that have two holes for secure mounting in industrial electrical installations.

• Common Models:
  • SDV-TSA: Typically used for lower current ratings (e.g., up to 32A).
• Performance: Rated for a short circuit capacity of 80kA at 415V, 50 Hz.
• Applications: Ideally suited for backup protection in motor starters and large-scale power installations.

• Low Power Loss: Designed for energy saving and "cool running" during operation.
• Current Limiting: Reduces thermal and electromagnetic stress to protect downstream switchgear.
• Safe Operation: No emission of gas or flames occurs during fuse operation

• Motor Protection: Frequently used for back-up protection to motor starters against short-circuit faults.
• Industrial Distribution: Protecting transformers, cable lines, and capacitor banks in modern electrical power plants.
• Safety: Designed to open circuits under heavy overload without damaging surrounding equipment

• Size A2 (TIA): Typical fixing centers are around 73mm. Common in ratings
• Size A3 (TIS): Typical fixing centers are around 73mm to 82mm. Ratings usually range from 35A to 63A.
• Size B1 to B4 (PCTC/PCTF): Used for higher current loads from 80A up to 400A. These central-tag types are available from manufacturers like Peco Electric
