Overview
The 3M 5319 motor lead pigtail splice is a professional-grade kit designed for reliable electrical connections in high-voltage motor applications. 3M Motor Lead Pigtail Splice Kits 5316-5319 Series are designed for splicing motor lead cables to incoming feeder cables, including the accommodation of inline connections at 1000 volts and less. This is a non-shielded splice system rated for 5–8 kV service, ideal for industrial motor lead terminations requiring durable, moisture-sealed connections.
Key Features
- 2-Hole Lug Configuration: Motor lead pigtail type for feeder cable range 250 MCM–500 MCM, motor lead range 4/0–500 MCM, voltage range 1000V, with 2-hole lug (pigtail) connection
- EPDM Rubber Construction: The slip on splice cover is made from EPDM rubber.
- Moisture Sealing: A mastic strip is used for the moisture seal.
- Multiple Splices Per Kit: The 3M Motor Lead Pigtail Splice Kit makes three splices.
- Stress Control: Includes high dielectric constant stress control for reducing the size and electrical stress.
- CSA Certified: Splice kits 5300–5319 are CSA certified for motor lead applications up to 600 Volts.
