Dold Solid State Contactor, 3-Pole, 3NO

Semiconductor contactors for wear-free, silent switching of AC loads such as heating, motors, valves and lighting
The cost of investing in this new technology is quickly recovered where high switching rates are used
Zero-voltage switching to prevent feedback to the main power grid
Integrated temperature monitoring ensures the device is protected from damage caused by excess current
In accordance with EN 60 947-4-2, IEC 60 158-2, VDE 0660 part 109
Single-phase or 3-phase design
Control input X1 with low power consumption, e.g. for PLC control
High switching frequency coupled with long service life
Compact construction with integrated heat sink
For switching AC loads up to 480 V
Protection circuit with varistors
Temperature monitoring via LED display and semiconductor output (memory preservation)
3 LED displays
Top-hat rail mounting

Semiconductor Contactors

A range of complete ’ready to use’ devices that comprise relay and heat sink in one compact DIN rail mountable unit. Typical applications include control of non motor loads where high operating frequencies are encountered.
