Circuit breakers are an essential safety device for most electrical circuits. They are designed to trip, or open, when a fault is detected, and effectively protect connected equipment from dangerous over-currents. A 1CU60R is an example of a type of circuit breaker designed to provide efficient, reliable, and safe protection of circuits. This article will explain the application field and working principle of 1CU60R circuit breakers.

Application Field

1CU60R circuit breakers are primarily intended to be used in low voltage circuits for up to 1000V. These circuit breakers are suitable for use in electrical installations for protection against short circuits and for overload protection of electrical motors, transformers, lighting, heating, and other electrical circuits. 1CU60R circuit breakers are designed specifically to provide enhanced protection against fire in electrical installations, effectively protecting any joined equipment. For improved safety, they are also provided with a manual deenergizing button to quickly deactivate the circuit breaker during an emergency.

Working Principle

1CU60R circuit breakers employ an electromagnet, which visualizes the overcurrent or short circuit within the electrical circuit. This electromagnet consists of a coil within the circuit breaker housing and an iron core surrounded by the coil. When a fault is detected and an over current occurs, the voltage in the coil greatly increases and generates a magnetic flux, which acts on the core, causing the circuit breaker’s contacts to open up. As the contacts open, the current flowing through the circuit breaker drops, thus protecting the connected equipment from a dangerous over current. When the fault is removed, the contacts close again and the circuit breaker is reset for the next fault.

The 1CU60R circuit breaker also features a manual switch, which can be used to manually reset the circuit breaker after the fault is cleared. In addition, the 1CU60R offers the option of additional protection against short duration faults by providing additional protection for the coil by means of a temperature indicator.

Ultimately, 1CU60R circuit breakers are intended to provide enhanced safety and protection for electrical circuits, while also providing reliable, efficient operation. They are suitable for a wide range of electrical installations, providing safe and secure protection against over currents and short circuits, while also offering improved fire protection.
