The switch is designed so to open a three-pole electric circuit when the pressure in the system rises and to close it when the pressure decreases.
- Designed for electric boilers of coffee machines as main application.
- UL approved (USA), SEV-ASE approved (Switzerland).

General Description
The ED101 series electronic module is used to control DSA/DWE/DWU pressure control valves. The module accepts up to 4 on/off input signals which select one of four pressures set by potentiometer adjustments on teh card. Two ramp adjustments provide smooth transition between selected pressures.

Relative and absolute pressure switch Type 615
Relative –1 ... 0 - 600 bar
Absolute 0 ... 0.3 - 16 bar
The type 615 pressure switches measure pressure by means of highly resistant ceramic elements. An open collector (transistor) output accommodates loads up to 100 mA. Either an N/C or N/O contact may be used, and the upper and lower switching point can be freely selected in the range 5 to100% fs. Various electrical and pressure connections are available to suit given applications.

The efector 500 is based on a ceramic measuring pressure cell which converts the measured quantity of pressure into a capacitive signal as a result of the deflection of a diaphragm. A microprocessor controls the evaluation of the electrical signal. For the efector 500 the system pressure is directly indicated on the unit by an LED display.
The extraordinary mechanical characteristics of the efector 500 result from the following design features:
The measuring pressure cell is designed in such a way that the diaphragm is supported by the base in the case of overload pressure. This leads to a high strength against hidden pressure peaks at values outside the measuring range.
The measuring pressure cell consists of ceramic which has ideal elastic features thus ensuring a high long-term stability of the diaphragm.
The electronic circuitry is made in film technology, i.e. a flexible, temperature-stable and extremely resistant polyimide film is used as a carrier for the SMD components. In conjunction with a special potting compound this leads to a high shock and vibration resistance.

Disconnectors and switch-disconnectors vertical break design SBC range
Description
The disconnectors and switch-disconnectors SBC range is visible breaking, vertical break design and principally used in rural distribution networks. They are suitable for horizontal or vertical mounting on metal, concrete or wooden single or double poles.
SBC types have a load breaking head comprising a chamber and fast opening auxiliary blade.
This arrangement combines the high speed action of the auxiliary blade with the cooling and confining effect of the enclosure to restrict the arc and limit the production of gases

Load break switch: switchblade with integral arc-strangler load breaking device for hinge-style mounting. This product includes a stationary core and a spring-loaded sliding sleeve which could quickly cut off the arc produced between the mounting contact and blade during load breaking operation.
Rated voltage: up to 15.5kV
Rated continuous current: up to 200A

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.
