Terminal connector Comap GW 15-3/4 (screw) – Comap J501 8501065

Comap GW 15-3/4 screw terminal connector (model J501) is a compact electrical connector designed for secure clamping of copper conductors in distribution and control circuits. It provides a fixed mechanical connection and reliable electrical continuity for building services and HVAC installations where screw-type terminals are required. The connector's design focuses on straightforward installation, durable contact under vibration and typical mechanical stresses, and compatibility with standard conductor sizes used in technical installations.

Advantages

The screw terminal design ensures stable mechanical fixation and consistent electrical contact without the need for special tools beyond a standard screwdriver. The compact form factor saves space in terminal blocks and junctions while maintaining clear access to screws for tightening and inspection. The connector is suitable for repeated connections and disconnections and is engineered to preserve conductor integrity under normal installation torque values.

Suitable for

• Fixed wiring in HVAC control panels and building automation systems
• Electrical distribution and control circuits in commercial and residential installations
• Terminal blocks, junction boxes, and control cabinets where screw connections are specified

Key specifications

• Connection type: screw clamping for copper conductors
• Construction: compact, single-piece connector suitable for panel mounting
• Conductors: compatible with standard solid and stranded copper wires within common installation gauges
• Mechanical fixation: screw-tightened clamp providing stable contact under vibration
• Application environment: indoor electrical distribution, control and HVAC systems

How to use

Prepare conductor ends by stripping insulation to the appropriate length recommended for the connector and ensure conductors are clean and undamaged. Insert the conductor into the terminal opening, then tighten the screw to the manufacturer's recommended torque using a suitable screwdriver to achieve secure clamping. For stranded conductors, use appropriate ferrules or ensure the conductor is formed to prevent stray strands. Verify mechanical and electrical continuity after installation and ensure screws are accessible for future inspection or maintenance.

Usage recommendations

Use the connector within specified conductor size ranges and tightening torque values; avoid over-tightening which can deform conductors or the connector body. For frequent reconnections of stranded wire, consider using ferrules to maintain reliable clamping. Inspect connections periodically in vibration-prone installations to confirm torque and contact integrity.
