Yaskawa's SF6 load break switches are safer to operate than vacuum and other competitive types because the gas pressure is continuously monitored by a pressure switch and is mechanically and electrically interlocked if pressure is lowered. Highest quality porcelain bushings are used for longer and more reliable insulation performance, thus making the Yaskawa switch ideal for use in hostile and dusty environments such as mines, heavy salt-ridden coastal areas, and dense tropical areas.
Yaskawa furnishes the load break switch in three application configurations.

General description:
EntelliGuard® G circuit breakers are the newest line of GE low-voltage circuit breakers, the next step in the evolution of a line known for its exceptional reliability and performance. They are available in 3- and 4-pole designs rated from 400A to 6000A, with fault interruption ratings up to 150kAIC
Integral to the EntelliGuard G breakers are the new, state-of-the-art EntelliGuard TU Trip Units, which provide superior system protection, system reliability, monitoring and communications.The breaker-trip unit system delivers superior circuit protection without compromising either selectivity or arc flash protection.
The EntelliGuard breaker-trip unit system demonstrates yet again GE's core competencies in reliable electric power distribution, circuit protection and personnel protection.
Modern economic reality and the regulatory environment demand system performance while recognizing the need to protect against the arc flash hazards that expose maintenance personnel to dangerous levels of heat, electrical energy, debris from damaged equipment and concussive forces. The challenge is to provide both better personnel protection by minimizing arc flash hazards and maintain electrical power to mission-critical loads. But these objectives often seem to conflict, pitting the speed and sensitivity required to optimize safety against the sequence of operations and interlocking required to maximize power system availability.

electric circuits. 1-pole circuit breakers are used for
voltages up to 220 V d.c.
and for higher voltages (up to 440 V d.c.) 2-pole circuit
