Circuit Breakers are essential devices used in the electrical engineering sector. In particular, the R14-S-SP-27412-1 is a type of circuit breaker that is especially designed to provide a dependable and reliable means of protection from electrical overloads. This article describes the application field and working principle of the R14-S-SP-27412-1 in detail.

Application Field

The R14-S-SP-27412-1 is a circuit breaker that is specifically designed for use in a variety of medium-voltage applications. This type of breaker is typically used in electrical distribution systems for applications such as substations, switchgear, transformers, motor control centers, and more. It has been tested and certified to be suitable for use in combination with other electrical equipment up to a maximum system voltage of 690V.

The breaker can be used in an extensive range of environments, including indoors, outdoors, in damp and wet areas, cold or hot environments, or in any area that may be subject to dust, liquid, or chemical contamination. It is also designed to be resistant to electrical surges and can be designed to trip or reset in less than 0.3 seconds.

The breaker is also unlike traditional fuses and is able to sense when an overload is present and can trip or reset itself to protect the electrical system, without being replaced. This makes it more cost-effective than traditional fuses as well as more reliable.

Working Principle

The R14-S-SP-27412-1 works by sensing when an overload is present and trips or resets itself to prevent the electrical system from any further damage. The breaker is constructed from a metal frame with a thermal-magnetic element. Inside the metal frame is the thermal-magnetic element which consists of a temperature-sensitive device, an electromagnet and a spring. The electromagnet is connected to two sets of contacts. The two sets of contacts are arranged so that when one set is closed, the other set is opened. The spring allows the contacts to open even when the heat sensitive device is not activated.

When an overload is detected, the electromagnet will activate and close the first set of contacts. This causes a high current to be drawn, which will cause the heat sensitive device to be activated. Once the device has been activated, it will open the second set of contacts and the breaker will trip, effectively resetting the circuit. Once the overload has been removed, the breaker will reset and the circuit will be capable of operating again.

The R14-S-SP-27412-1 also has a number of features which make it a reliable and safe device. The breaker is designed to be shockproof and can be set to trip at a predetermined current level. In addition, it is temperature-resistant and has a wide operating temperature range.

Overall, the R14-S-SP-27412-1 is a highly dependable and reliable circuit breaker that can be used in a variety of applications. It is designed to provide protection from electrical overloads and has a number of features that make it an ideal choice for use in medium-voltage applications. The working principle of the breaker is based on the thermal-magnetic principle and allows for it to trip and reset itself to protect the electrical system. As such, it is an essential device for electrical engineering systems.
