Product Description
The Expulsion Fuse Cutouts consist of a reliable mechanism. It is used for protecting Arial distribution systems for voltages ranging from11 kV to 36 kV. It is designed to be installed outdoors for vertical cross arm or pole mounting. These cutouts are available in both Porcelain & Silicone rubber insulators. the Expulsion Fuse Cutouts has steel hooks mounted on the top support guide into the contact and also serves a dual purpose for use with load break tools. The holder has clearly distinguished outer layer of UV resistant fibre glass and inner layer of bone liner which effectively extinguishes the Arc.

Features:
  • The fuse carrier tube is replaceable with a new one in an unlikely event of being damaged or burnt.
  • The hinged mechanism is made from brass and is duly electroplated ensuring smooth operation in corrosive environments and provides low resistance current transfer path.
  • With the incorporation of Arc Shortening rod, higher interruption capacity is achievable. The Arc Shortening rod is optional and is available on request.
Expulsion Fuse Cutouts:
  • It has a safety latch which prevents the fuse carrier from dropping due to vibration. 
  • It can be used as off load disconnector with Brass Blade instead of Fuse holder.
