Circuit breakers are an important safety feature in any home, office, or other building. The 1CU50R is a specific type of circuit breaker used in a variety of applications. This article will discuss the 1CU50R application field and working principle.

1CU50R Application Field

The 1CU50R circuit breakers are designed for use in medium voltage (MV) systems. They are most commonly used in electric power distribution and system protection equipment. They are suitable for use with cables and overhead lines, as well as for the protection of motors, transformers, and other equipment. The 1CU50R can also be used in industrial switching applications. The switches are capable of handling current up to 6,300A and voltages up to 1kV.

The 1CU50R is suitable for use in both indoor and outdoor environments. They are designed to be robust and durable, and are ideal for use in tough conditions, such as extreme temperatures, vibration, and hostile environments. The breakers are also corrosion-resistant, meaning they can withstand the harsh conditions of many industrial locations.

1CU50R Working Principle

The 1CU50R has a proven design that is reliable and easy to use. The breaker uses a standardised three-pole operation. Each pole is made up of two interlocking frames, with one stationary and one operational frame. The two frames are held together by a spring-loaded latch connected to a pivot ring. This allows for a reliable, efficient operation.

When the current passes through the 1CU50R, the frame contacts are activated and current can flow. When the current reaches a dangerous level, the current will pass through the primary contacts, and the contacts will open, cutting off the power supply. This switching action is done mechanically, without the need for an external power supply.

The 1CU50R also has an overload protection system. This ensures that the breaker will trip if the current reaches a dangerous level. This safety feature prevents the breaker from being damaged due to excessive current. The system also has an instantaneous trip function, which will trip the breaker if the current is too high. This prevents any potential damage to the equipment or wiring due to excessively high current.

The 1CU50R has a high short-circuit current rating (SCCR). The SCCR is a measure of the current that the breaker can safely handle without tripping. The 1CU50R has a SCCR rating of up to 10kA, making it suitable for use in a range of industrial applications.

Conclusion

The 1CU50R is a reliable, durable circuit breaker that is suitable for medium voltage applications. The 1CU50R has a proven design and is capable of handling currents up to 6,300A and voltages up to 1kV. Its overload protection system and instantaneous trip function ensure that the breaker will always provide the necessary protection. The 1CU50R is a cost-effective solution and is suitable for use in a wide range of industrial applications.
