Circuit breakers are devices that have the ability to physically disturb an electrical flow when too much current is present, usually due to an overload, fault, or other type of abnormality. The R11S-4-12.0A-39508-12 is a specific type of circuit breaker commonly used in systems with higher current requirements.

This circuit breaker was designed specifically for applications such as AC motors, air conditioners, pool pumps, and heaters. It operates similarly to other breakers, being able to detect when the amount of current flowing through it exceeds a certain limit and will trip, cutting off the power to the circuit. This prevents the risk of electrical shock and damages to the device that could be caused by an over-current situation. The R11S-4-12.0A-39508-12 breaker features a trip curve of I-L that can range from 230 to 780A. It also is equipped with a trip delay of 280 to 3500A, and comes with a trip curve of I-t that is adjustable from 0.22 to 0.55A/s.

The working principle behind the R11S-4-12.0A-39508-12 circuit breaker is based on the thermal-magnetic effect. This is a method in which the current is measured by two separate elements; the thermomagnetic element measures the amount of current and trips the breaker when the current reaches a certain set limit. The thermal element, on the other hand, measures the temperature at which the current is being pulled along. This technology allows for a much more accurate and reliable operation, as the circuit breaker takes into account both the current and the temperature before tripping.

The R11S-4-12.0A-39508-12 circuit breaker has a wide range of applications and is the ideal choice for use in higher energy demand systems. It features a current range of 230A up to 780A, with a trip delay of 280 to 3500A, and a trip curve of I-t adjustable from 0.22 to 0.55A/s. For applications such as AC motors, air conditioners, pool pumps, and heaters, the R11S-4-12.0A-39508-12 circuit breaker is the perfect choice for providing reliable protection to these and other devices. Additionally, its thermal-magnetic principle ensures accurate and reliable operation while protecting the device from over-current situations and potential electrical shocks.
