It has everything which characterizes a true professional.
It is reliable; it is safe and functions absolutely economically.
Its area of use: In all the world's climate zones.
Its references: Used in over 80 countries worldwide.
It is called 3AP1/2 and it is the high-performance high-voltage circuit-break with stored energy spring mechanism from Siemens.

For all uses: reliable and economical
SIEMENS decades of experience in high-voltage switching technology went into the design and production of the 3AP1/2 circuit breaker. We produce all the crucial components of the circuit breaker ourselves, according to the well-known Siemens quality standards.
SIEMENS quality management system, which is certified according to DIN ISO 9001, guarantees guarantees that our quality remains at the same high level: regular management review, internal audits in every department and the constant documentation of all processes. All systems, for example the stored energy spring mechanism and the interrupter unit, have proved themselves in daily use throughout the world.

Safely available any time
Another of its strengths: the 3AP1/2 high-voltage circuit breaker safely operates and is capable of bearing high loads. Particularly strong porcelain for the insulators, and breaker frames optimized by using the latest calculation techniques, give it a very high seismic stability under load.
It performs to its full potential over its entire service life-we guarantee this.

Simply unbeatable: the service
The 3AP1/2 high-voltage circuit breaker gives years of safe and reliable operation. And, in case it does fail, you can rely on our worldwide range of services. Inspection, maintenance, repair and a 24-hour fault service give you the necessary security.
