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.

APO: Active Safety for High Voltage Systems
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.
