Product Details

The Havells IHFSTW4250 is a rugged and reliable 3-pole Switch Disconnector Fuse Unit rated at 250A, designed for safe and efficient power isolation in medium to heavy-duty electrical installations. Built for industrial panels, transformer feeder units, or motor control centres, it ensures mechanical disconnection and fuse-based protection in a single, compact form. This unit is capable of safely isolating electrical loads during maintenance or fault conditions while simultaneously safeguarding downstream circuits with HRC fuses against overcurrent's and short circuits. Engineered from robust insulating materials and conforming to IS/IEC standards, the unit features a high thermal withstand capacity, arc suppression design, and silver-plated contacts for enhanced conductivity and long service life. The ergonomic rotary handle enables smooth operation even under load, and the unit is fully shrouded to prevent accidental contact with live parts.
