Sigma Open Type Power Swans are safely used in applications that require high performance requirements, high-circuit cutting capacities, wide operating temperature range and high electrical-mechanical life.
. 
What are the Open Type Power Swear General Application Areas?
As the main entrance switch, in the protection, switching and selectivity of the general electrical system;
In the protection and switching of large power motors, generators, transformers;
Used for protection, switching and mechanical locking in transfer applications between suitable accessories and 2 power supply.
Sigma Open Type Power Switch Protection Functions?
Sigma Open Type Power Swanses Thermal-Magnetic-Solarak error protection thanks to the electronic opening unit.
In the range of
(0.4-1)*Adjustable Thermal Protection
(0.4-15)*Adjustable Magnetic Protection
In the range of
(0.2-0,8), adjustable soil error protection
Sigma Open Type Power switches guarantee the selectivity in the electrical system with the ability to add time delay to the above -mentioned error cases. In other words, the Sigma Open Type Power switches detect the error flow when used as the main input switch, but waits for the time set by the user without moving to the trip position. Thus, first of all, the defective area connected to the sub -groups of the electrical installation allows the insulation of the defective area from the main system and prevents the entire electrical system from remaining energy.
L - S - I - G Time setting functions
Long Time Delay ”with thermal protection long -term delay setting
S "Short Time Delay" thermal protection short -term delay setting
Magnetic protection delay with "Instantantaneous Tripping Delay"
G “Ground Fault Delay” is provided with soil error flow delay adjustment.
Open type switches protection functions, as well as the electronic unit,
Phase voltages show on the LCD screen by measuring phase currents.
Shows the error current and error time of the switch on the screen at the time of opening.
offers the phase information to which the error occurs to the user.
What is the difference between drawer and fixed type open type power switches?
There is no difference between drawer -type open type power switches and fixed open -type power switches in terms of protection functions, with the help of the drawer with drawer and the main body in the drawer type switches, the maintenance repair process is carried out quickly and easily. In drawers with drawers, when the test is taken to the wood, the care of the switch is provided and the control of the functions is provided without the system without energy.
