The Ground Fault Circuit Interrupter (GFCI) is a life-saving protective device that detects current imbalances in electrical circuits and instantly cuts off the circuit within milliseconds in the event of an electrical leak. Its primary function is to measure the current difference between the phase and neutral in electrical installations, protecting people from electric shock and structures from fire risks caused by ground faults.

Sigma Ground Fault Circuit Interrupters, which make a difference with domestic production technology, protect human life in direct or indirect contact with electrical leaks while also preventing fire risks caused by insulation faults, ensuring life and property safety.

Produced in full compliance with TS EN 61008-1 standards and CE norms, Sigma Residual Current Protection Switches combine quality with domestic engineering power.

The new Sigma 10mA Threshold Residual Current Circuit Breaker;

The new Sigma 10mA threshold Residual Current Circuit Breakers are specially designed to protect people from electric shocks in water environments with high conductivity, such as swimming pools, ornamental pools, baths, and saunas.

When a person is floating in water and exposed to a current of 15mA - 20mA, their muscles lock up and they become unable to move. 

If a person is exposed to a current of 15mA - 20mA while swimming in water, their muscles lock up and they become unable to move. This limit, known as the “Release Threshold,” is around 10mA for the average adult. The new Sigma residual current protection switch ensures complete safety in hazardous water environments by cutting off power at just 7-8mA levels, even before reaching the critical threshold of 10mA.
