Decisive advantage – no compromise in quality with affordable price
Sigma Low Voltage Contactors are produced suitable according
to TS EN 60947-4-1 standards as 3 poles. As mentioned in TS EN 60947-4-1 standards they are used safely in different categories for switching
and remote control of motors, lighting systems, compensation systems and various
inductive loads. When LV contactors are used together with
Thermal overload relays, they protect the circuit against overload current
A concept with a future – design follows function
- 5 different size from 9A upto 150

- Opportunity for different using class
- High Mechanical and Electrical life
- Appropriate for 35mm DIN Rail and screw mounting
- Wide accessory opportunities
- 9-22A 1NO+1NC Standard aux. contacts
- 32-150A 2NO+2NC Standard aux. contacts
- AC and DC controls voltage opportunity
- Safe working at low voltage
- Ip20 protection degree
Contactors For Capacitor Switching
They are designed as a particular for controlling the 3 poles condenser.
Thanks to special blocks connected to the current limiting resistance
which is on the Contactors they hinder cleaving the main contacts
of the Contactor to each other by limiting the high peak currents
till 70 times of maximum rated current and this lengthen contactor’s life.
Sigma Capacitor Contactors are specifically designed to handle the unique application requirements for single or group PFC. The resistors work
in conjunction with a special early-make auxiliary contact to pre-charge the capacitors so the main contacts do not see the peak inrush. After
the pre-charge, the main contacts then close after a time lag and conduct continuous current.
A Reversing Magnetic Contactor is the product built by combining two standard magnetic contactors by use of a highly reliable mechanical
It is suitable for use in direct-reverse operation, plugging and transfer between commercial and noncommercial power source for a motor..
Thermal Overload Relays
Sigma Thermal Overload Relays protect its connected motor Circuits against overcurrent and phase loss.
Thermal Relays ,produced according to TS EN 60947-41, have such a features that they can be used beside its
connected contactors can be used also with 35mm DIN rail adaptor as seperately.
