What are tertiary spreads and what is the difference with residential spreads?
Tertiary earth leakage circuit breakers are a type of earth leakage circuit breaker used in industrial and commercial installations to protect against abnormal currents. Unlike residential differentials, tertiary differentials are designed to withstand higher currents and voltages, and to protect against a wider variety of abnormal conditions.
Tertiary differentials are used in commercial environments to protect people and equipment against earth leakage currents, and also to protect equipment against overloads and short circuits. These devices are designed to withstand the toughest working conditions and to provide reliable protection in a wide range of industrial and commercial applications.
In addition to being more robust and resilient, tertiary differentials are also have a different firing curve compared to residential differentials. While residential differentials usually have a type C tripping curve, tertiary differentials may have type B, C or D tripping curves.
The tripping curve refers to how the device responds to an abnormal current. Curve C is more sensitive and activates quickly at small currents, while curve D is less sensitive and activates only at higher currents. Curve B is an intermediate curve between curves C and D.
In a commercial environment, it is important to have an adequate tripping curve to ensure efficient protection against abnormal currents. The tertiary differentials with curve B, C or D are adjustable according to the needs of each installation and are more suitable for environments with higher currents and voltages.
