Is our newest addition to the range and is in response to an ever pressing demand to reduce the switchgear foot-print. Primacon is designed for a paradigm shift in IMCC projects, offering all of the protection and control functions required for motors, yet housed in a compact enclosure.



Primacon is available with 1 of 2 CT connection options, either pass through internal CTs rated at 29A nominal (as shown above) or for use with LPCT’s (low power current transformers – shown below) allowing primacon to connect to circuits of any size determined by the rating of the LPCT, e.g., 100A:225mV




Designed for 35mm DIN mounting and measures just 100x100x50mm with integrated pass through CTs for FLCs upto 29A. Primacon has been extensively tested for withstand to heat rise and high temperatures to satisfy ourselves of its performance in the smallest of withdrawable motor starter cubicles and those without forced air circulation.


To avoid issues associated with exchanging withdrawable starter cubicles in LV switchgear, such as storing the relay parameters and serial address with the motor and cubicle position and not the starter drawer or tray. Primacon makes use of a remote memory module so that those critical settings remain static, which improves ease of use, flexibility and starter interoperability.
