Circuit Breakers: CR15-52-6.00A-36040-2-V Application Field and Working Principle

Circuit breakers are electrical safety devices used to protect electrical circuits from damages due to overload or short-circuit. Circuit breakers can be manual or automatic, and are available in different types depending on the amperage rating and application. In this article, we will discuss the application field and working principle of the CR15-52-6.00A-36040-2-V Circuit Breaker.

Application Field

The CR15-52-6.00A-36040-2-V Circuit Breaker is a thermal-magnetic circuit breaker with a current rating of 6A and a voltage rating of 400VAC. This makes it suitable for a variety of applications, such as domestic and commercial equipment, power distribution systems, and industrial plant protection. This breaker is a UL 489 approved device and can be used in a variety of applications, such as low voltage, power, lighting and overload protection.

In addition to its 6A current rating, the CR15-52-6.00A-36040-2-V circuit breaker also has a short-circuit capacity of 10KA. This makes it suitable for applications where higher short-circuit protection is required. The device is also available in a variety of mounting options, such as Din Rail mounting, panel mounted, or flush mounted. It also has an LED indicator, which indicates the status of the device.

Working Principle

The working principle of the CR15-52-6.00A-36040-2-V Circuit Breaker is based on the thermal-magnetic protection principle. It utilizes a bimetallic strip and an electromagnet to detect and interrupt fault currents. The bimetallic strip is composed of two metals that have different expansion rates when exposed to heat. When current passes through the circuit breaker, the bimetallic strip expands due to the heat generated, causing the contact points on the strip to separate and open the circuit. This interrupts the current flow, preventing any further damage to the circuit or the device.

The electromagnet works by detecting changes in the magnetic field caused by fault currents. When the current cross a certain threshold, the electromagnet activates, causing the contact points on the bimetallic strip to separate and open the circuit, thereby interrupting the current flow. The short-circuit protection of the CR15-52-6.00A-36040-2-V circuit breaker also uses an electromagnet and bimetallic strip, but in this case, the electromagnet is used to detect high fault currents and trip the breaker instantly, before any damage can occur to the circuit.

Conclusion

The CR15-52-6.00A-36040-2-V Circuit Breaker is a thermal-magnetic circuit breaker with a current rating of 6A and a voltage rating of 400VAC, making it suitable for applications such as domestic and commercial equipment, power distribution systems, and industrial plant protection. The circuit breaker works using a bimetallic strip and an electromagnet, which detects and interrupts fault currents by breaking the circuit. The device also has a short-circuit protection capacity of 10KA and is available in several mounting options, with an LED indicator to indicate the status of the breaker.
