Switch Disconnectors Fuse Units

We supply Switch Disconnectors Fuse Units DIN and BOLT Type (Open Execution) that are fabricated using quality raw material. These are manually operated three pole switches with neutral, which has a provision to connect load at either side of the terminals. During 'OFF' position of unit, fuses are being isolated from both sides and can be safely removed at the time of maintenance or replacement. Designed in compliance with IEC: 947-3, IEC: 664 and IS: 13947 Part (I&III) - 1993 quality standard, these unit ensure high breaking, long contact life and safety under short circuit conditions.

Features:

• Multiple roller contact system - more number of breaks, per pole and self cleaning action to ensure trouble free performance and longer electrical life.
• Mechanical movement over roller balls for faster action and least fraction resulting in longer life.
• Quick make & quick break front operated mechanism.
• Unbreakable Fiber Glass moulded handle with door interlock and pad lock facility.
• Adjustable telescopic shaft by which switch can be easily installed in panels of different depth.
• While breaking the circuit, guaranteed sufficient air sectioning clearance.
• Compact & standardized sizes for range 63A- 800 A ideal for switch board manufactures.
• Mounting is possible in both horizontal & vertical positions.
• Barrier Plates between fuses.
• Protection against over current & short circuit faults of high rupturing capacity upto 80 KA.
• Ideally suitable for Power Control Centres (PCC).
• No movement of fuses - Ensure long mechanical and electrical life of fuse switch.
• Both DIN type and BOLT types switch fuse disconnectors are available.
• Suitable for AC 23A duty-most severe utilization category.
