Spring clamp terminal block Relpol GZ2-1060, model GZ2 R2M, screwless connection

The Relpol GZ2-1060 spring clamp terminal block model GZ2 R2M offers a screwless connection for electrical conductors using an internal spring mechanism. Designed for compact mounting in control panels and distribution systems, this terminal block provides vibration-resistant contacts and tool-free insertion and removal of conductors. The construction supports fast wiring and maintenance where secure, reliable termination is required in a small footprint.

Advantages

This spring clamp terminal provides consistent contact pressure that compensates for conductor relaxation and vibration, reducing the need for retightening. The screwless design allows quick, tool-free conductor insertion and removal, speeding up assembly and servicing. Its compact form factor saves space on DIN rails and simplifies wiring layouts while maintaining electrical continuity and mechanical stability.

Suitable for

• Control panels and industrial switchgear
• Distribution boards and terminal cabinets
• Machines and equipment subject to vibration
• Fast assembly and maintenance tasks

Key specifications

• Connection type: spring clamp (screwless) for direct conductor insertion
• Mounting: DIN-rail compatible compact housing
• Conductor accommodation: solid and ferruled conductors suited for spring terminals
• Contact design: vibration-resistant spring contact ensuring stable electrical connection
• Material characteristics: durable insulating body and corrosion-resistant contact elements
• Operational use: designed for low-voltage control and distribution wiring

How to use

Strip the conductor insulation to the required length, ensuring the conductor end is clean and free of damage. Insert the conductor straight into the terminal entry until it seats against the contact; the spring mechanism will clamp the conductor without the need for a screwdriver. For removal, use the designated release method if provided (for example a small tool or push-button on the terminal) or pull the conductor out while pressing the release mechanism, following manufacturer guidance. Verify secure seating by a gentle tug test and ensure correct polarity and numbering when wiring multiple terminals.

Usage recommendations

Use conductors and ferrules sized according to the terminal’s recommended cross-section range and follow panel layout practices to avoid overcrowding. Perform periodic inspections in high-vibration environments to confirm long-term contact integrity. Always de-energize circuits before wiring or maintenance and follow applicable electrical standards and safety procedures.
