Parallel Arc fault detection
AFCBs combine the safety of standard Circuit Breakers and high accuracy electronics to mitigate arcing. Each standard thermal Circuit Breakers is equipped with an electronic board in order to analyze the current waveform in real time to detect if arcing is occuring.
Ground Fault detection
The Ground Fault Arc Fault Detector (GF-AFCB) provides built-in test features that allow aircraft maintenance personal to verify that ground fault has occured: Data issued from the led gives this information.
SSCB
The solid-state breaker concept eliminates the traditional moving parts of an electromechanical circuit breaker, using semiconductors and advanced software algorithms to control power and interrupt extreme currents more quickly than ever before. This also enables a SSCB to provide more than just thermal protection; its role encompasses electrical functions such as: relay, gradator, chopper, ground fault, soft start, current measurement. These functions can be used for light dimming, motor speed control, intermittent load command (on/off), inrush current limitation, sequential power ON of loads, load failure detection.

Remote Control
Discover our Remote Control Circuit Breakers
The RCCB merges a circuit breaker and a contactor function in one single case. Allowing you to open and close the contactor at a distance just by applying a 28 V command input.
Built to last
Our RCCBs can commute at least 100,000 times! i.e 50,000 flying cycles on a cargo doors application considering take-off and landing.
