Circuit Breakers - R11-52-5.00A-36833-5-V

Circuit breakers are a type of electrical device that detects broken or overloaded circuit lines and is designed to protect the line, its equipment and its users from damage. The R11-52-5.00A-36833-5-V is an example of a circuit breaker and its application fields and working principles are explored in this article.

Applications

The R11-52-5.00A-36833-5-V circuit breaker is a manually operated switch which is a direct replacement for the Square D series. It has a voltage rating of 120/240 volts and is designed for overhead, underground and pad mount applications. The breaker can be used as an isolation switch to protect circuit elements in the event of an overload or to disconnect the power supply to a faulty circuit. In addition, it can also be used to control the flow of electricity in residential, commercial and industrial applications.

The R11-52-5.00A-36833-5-V breaker is UL Listed, CSA certified, meets all UL 489/CSA C22.2 standards, and is rated for operation up to 80°C. It also features a quick-make, quick-break snap-acting switch mechanism and flange-mounted end clips for easy installation.

Working Principle

The R11-52-5.00A-36833-5-V circuit breaker is equipped with a bimetallic strip, which is composed of two strips of dissimilar metals that are bonded together. When the circuit breaker is closed, the current passes through the bimetallic strip, heating it up. As the temperature rises, the two metal strips start to expand at different rates, resulting in a slight bend in the strip.

The bend in the strip makes contact with the internal switch contacts, which then trips the circuit breaker. The trip occurs when the prespecified current threshold is exceeded, causing the bimetallic strip to expand more, breaking the circuit and turning off the power to the line. This helps to prevent damage to the line and its equipment from over-current.

Furthermore, when the R11-52-5.00A-36833-5-V breaker is tripped it will remain in the off position until the reset switch is activated. This helps to prevent the circuit from being restarted until the source of the over-current has been eliminated and the reset switch is activated.

Conclusion

The R11-52-5.00A-36833-5-V circuit breaker is designed to protect circuit lines and equipment from excessive current and is suitable for use in residential, commercial and industrial applications. It is equipped with a bimetallic strip, which detects excessive current and trips the breaker, and a reset switch that prevents the circuit from being restarted until the source of the over-current has been eliminated.
