To meet the diverse industry and application needs across the globe, we offer a wide range of Terminal Blocks in 5 different connection technologies.

Push-In Connection Technology offers an innovative, tool-less wiring solution, ensuring a fast, reliable, and vibration-resistant connection. This technology allows users to simply push solid conductors or ferrule-crimped wires into the terminal block for a secure connection, eliminating the need for screwdrivers or any additional tools.
The Push-In system utilizes high-quality stainless steel springs to maintain consistent contact pressure, ensuring a gas-tight and vibration-proof connection. This method drastically reduces installation time while increasing reliability, particularly in applications that require frequent assembly and disassembly.
Tool-free installation: simple push-in of wires without tools.
Time-saving: Reduces installation time by up to 75% compared to traditional methods.
Vibration resistance: A pre-stressed spring ensures secure connections even in high-vibration environments.
Safety: Reliable, gas-tight connections provide increased safety and long-term stability.

Spring Clamp Connection Technology is particularly suited for applications with high vibrations and high thermal cycling. Terminals with spring clamp technology have specialised high-tensile springs, that clamp down onto the wire, ensuring constant pressure over time and under varying environmental conditions. The spring mechanism allows wires to be securely connected without the need for screws or additional clamping mechanisms.
Spring Clamp Technology is designed to accept both solid and stranded wires, offering flexibility across various industrial applications.
Screwless connection: No tightening of screws required for reliable connections.
Time-saving: Reduces installation time by up to 50% compared to traditional methods.
Vibration resistance: Pre-stressed springs ensure secure connections even in high-vibration environments.
Safety: Reliable, gas-tight connections provide increased safety and long-term stability.

Screw Clamp Connection Technology is a reliable method widely used across industries. In this technology, a screw is used to tighten the clamp, which brings the connected wire in contact with the current-carrying element, creating a strong and secure connection. The torque applied during tightening ensures a firm and secure contact, making it highly effective in high-current applications where robust connections are crucial.
Versatile connection: Most popular connection method.
Global Approvals: A wide range of product and industry-wide approvals.
Vibration resistance: Specialized alloy steel clamps with integral locking feature prevents self-loosening of screws.
Safety: Reliable, gas-tight connections are made because of a large contact area between the clamp and the current carrying element.

Stud & Bolt Connection Technology is designed for high-current, heavy-duty applications. This method uses bolts and nuts to secure wires to the terminal, ensuring a reliable and robust mechanical connection. It is especially suited for connecting large-gauge wires in environments where high electrical loads are common. The connection ensures long-term stability even in harsh operating conditions.
Robust connection: Most popular connection method for heavy duty applications.
Global Approvals: A wide range of product and industry-wide approvals.
Vibration resistance: Specialized locknuts and spring washers prevent loosening of connections.
Safety: Reliable, gas-tight connections are made because of a large contact area between the crimped wire and the current carrying element.

Spring Loaded Screw Connection Technology is a hybrid system that uses a spring to maintain consistent pressure on the wire while the screw ensures a robust mechanical connection. The spring compensates for any loosening of the screw over time, providing a maintenance-free solution that ensures constant contact pressure even in environments subject to vibration or thermal expansion.
Specialized connection: The best of both worlds, with a screw clamp connection being secured with an additional spring.
Industry-Specific Approvals: Compliance under CEGB regulation, especially for SEC and NTPC panels.
Vibration resistance: Additional spring prevents self-loosening of screws.
Safety: Reliable, gas-tight connections are made because of a large contact area between the clamp and the current-carrying element.
