Product Description
The Burndy QR40 is a high-conductivity, heavy-duty copper mechanical splice designed to join and reduce large-gauge cables. Specifically engineered for transitions between 600 MCM and 800 MCM conductors, this connector ensures a secure, low-resistance electrical joint. Its compact 3-5/8 inch length and robust bolt-down design make it ideal for industrial power distribution, panel boards, and large motor terminations where space and reliability are critical.
