What are Terminals and Terminal blocks?

SNK Terminals are a type of industrial control terminal that is used in industrial automation, process control, and other applications. These terminals are designed to provide a secure and reliable connection between the user and the machine. They are typically used to control machinery, monitor production processes, and manage data. SNK Terminals are available in a wide range of sizes and configurations, allowing them to be used for many different types of applications.

Modular terminals are components that can be used to connect two or more devices together in a network. They are typically used to connect computers, servers, routers, switches, and other network devices. Modular terminals are often referred to as RJ-45 connectors because they use an 8-pin RJ-45 connector.

A terminal block is a type of electrical connector used to connect two or more wires together. It typically consists of a metal or plastic housing containing multiple terminals, which are the points at which the wires are connected. Terminal blocks are commonly used in industrial and commercial applications to provide a secure connection between electrical circuits.

Wieland gesis® NV Signal Connector

The connector system for quick, easy, and safe bus cabling and signal applications. It meets all the requirements of modern building installation.

Low-Voltage Technology
These connectors are used to distribute signals in buildings, in parallel to the distribution of power. Mechanical coding and clear assignment with different colors facilitate assembly. Complex installations can be realized with just four basic components – from the sub-distribution unit to any point of use. The connectors come as male and female connectors complete with strain relief and can be used to connect any current type of cable.

The BST14 are designed according to the KNX manual.

The 5G2.5/4+2X1.5 flat cable with shielded bus, as per the KNX manual, is available for the combined distribution of energy and signals.

Schurter APO: Pyrofuse

APO: Active Safety for High Voltage Systems

Quick Response
Triggered actively
Low temperature rise
Reliable Operation

Electrification is advancing across all industries – from electric vehicles and charging infrastructure to energy storage, aerospace, and fuel cells. As a result, the demand for reliable protection mechanisms in high-voltage systems is increasing. With the new Pyrofuse-APO Series, Schurter launches a fuse technology that sets a new benchmark for safety.

Unlike conventional fuses, the APO Fuse operates actively. In the event of a short circuit or accident, the control unit sends a trigger signal to an integrated micro gas generator. Within milliseconds, the generator produces high pressure that drives a piston to mechanically sever the solid copper busbar. The resulting arc is safely suppressed in a dedicated extinguishing chamber. The outcome is a complete galvanic isolation in less than two milliseconds – with measured values as fast as 0.9 ms.

The APO Series is rated for operating voltages up to 1000 volts and continuous currents up to 400 amperes. With an ultra-low internal resistance in the range of only a few dozen micro-ohms, power losses and temperature rise remain minimal. Its high breaking capacity ensures safe interruption even under extreme short-circuit conditions, while the fully encapsulated design prevents the release of gases or particles.

This unique combination of speed, robustness, and efficiency guarantees maximum system safety. At the same time, the compact design allows for seamless integration into existing architectures and relieves downstream components such as contactors.

With the Pyrofuse-APO Series, Schurter strengthens its position as a technology partner for emobility and the energy transition. Whether in electric vehicles, aerospace applications, or stationary storage systems, the APO Fuse ensures that high-voltage systems remain reliably protected – even under the most demanding conditions.
