R21-4-2.00A-9191-1-V

Circuit breakers are electrical components specifically designed to protect other electrical components, including switches, wires, and appliances, from sudden disturbances. The R21-4-2.00A-9191-1-V circuit breaker is used to provide overload and short-circuit protection in low voltage motors, generators, transformers, wind turbines, and other AC applications. This circuit breaker works by detecting an overload or short-circuit current and then automatically opening the circuit to interrupt the flow of electricity. As a result, it not only prevents damage to your electrical components but also prevents injury or even death due to electrocution.

The R21-4-2.00A-9191-1-V circuit breaker provides instant current protection with extremely low by-pass leakage current. This is due to its design, which features two independent breakers. Each breaker has its own sensitive current detection mechanism and will open the circuit when the current exceeds the set point. The sensitivity of the circuit breaker can be adjusted for different applications, providing effective protection at currents as low as 0.25A.

The R21-4-2.00A-9191-1-V circuit breaker is designed to be stress-resistant in the most demanding applications, including those in a harsh environment. It is rated at 16A / 9.5kA, which means it can handle almost any kind of circuit overload or short-circuit current. The breaker is temperature-resistant and vibration-resistant, which makes it ideal for use in high-vibration environments. Additionally, it has an operating temperature range of -40°C to +80°C, giving it an extra layer of protection against extreme heat or cold.

Unlike other circuit breakers, the R21-4-2.00A-9191-1-V circuit breaker is tripped by a thermal-magnetic action. This means that the current path is interrupted by a combination of heat and magnetic force. This type of protection is best for AC circuits, as it allows for instantaneous response to changes in current. As soon as an overload or short-circuit current is detected, the breaker trips, thus preventing further damage to your electrical components. The breaker also features a fast reset time of 10 ms, meaning that the circuit breaker can be reset quickly in the event of an overload or short-circuit.

In addition to providing superior protection against overloads and short-circuits, the R21-4-2.00A-9191-1-V circuit breaker is also designed to prevent nuisance tripping. This is done by using temperature-compensated current limitation and integrated surge protection. The temperature-compensated current limitation ensures that the breaker is not tripped too easily, while integrated surge protection helps protect sensitive electronic components.

The R21-4-2.00A-9191-1-V circuit breaker is a reliable and efficient device for protecting AC circuits. With its advanced features, it provides superior overload and short-circuit protection at a competitive price. It is the ideal circuit breaker for any application where reliable, fast protection against AC overloads or short-circuits is needed.
