Circuit breakers are an essential part of a power system, protecting it against short circuits and overloads. Circuit breakers come in many shapes and sizes, and their working principles and applications vary. This article will look at the 1C8UL circuit breaker, discussing its application field and working principle.

1C8UL is a miniature circuit breaker manufactured by Schneider Electric. It is used to protect circuits against overloads, short circuits, and ground faults. It can be installed in shallow circuit breaker boards or in any other type of enclosure. The 1C8UL breaks and makes the electrical circuit with a push-to-reset switch, allowing circuit breakers to be reset without disconnecting the power. It can also be used as a disconnector in certain applications. The 1C8UL has a current rating of 8A and is UL 489 and CSA certified.

The 1C8UL circuit breaker works on the principle of thermal magnetic tripping. This type of circuit breaker relies on the thermal effect of an overload and the magnetic effect of a short circuit to trip the breaker and break the circuit. The thermal effect occurs when the current in the circuit exceeds a predetermined value for a period of time. This causes the temperature of the breaker to rise, activating a thermal tripper. The magnetic effect occurs when the current in the circuit reaches a pre-set value in a very short time, whereupon a magnetic field is generated which trips the breaker.

The 1C8UL is designed to protect circuits in electronics, telecommunications, and other industries. It is commonly used to protect personal computers, telephones, radios, fax machines, and other types of equipment. It can also be used in industrial applications such as control systems and automation systems, as well as in residential installations.

The key benefits of the 1C8UL circuit breaker are its size and ease of installation. The breaker is small and easy to install, and can be used in shallow circuit breaker boards or any other type of enclosure. It has been approved for use in enclosure types 1 and 2 according to IEC 60529, and has a leakage current of no more than 5mA.

The 1C8UL circuit breaker is a reliable and safe solution for protecting circuits against overloads, short circuits, and ground faults. Its compact size and ease of installation make it ideal for use in a variety of applications. It is UL 489 and CSA certified, and has been approved for use in enclosure types 1 and 2 according to IEC 60529.
