UPGF6-30421-18 Circuit Protection

When selecting circuit breakers, one of the main considerations is the voltage and current rating, as this determines the size and type of circuit breaker that should be used. However, other factors that need to be taken into account include the working principle and application field of the circuit breaker. One such circuit breaker is the UPGF6-30421-18, which is suitable for use in a variety of application fields.

The UPGF6-30421-18 is a compact, current-limiting circuit breaker that is designed to protect electrical circuits from overcurrents. The UPGF6-30421-18 is a type of fuse-link circuit breaker, which means that it is designed to open the circuit automatically when the rated current is exceeded. The UPGF6-30421-18 is equipped with a replaceable fuse-link, which is designed to break the circuit and isolate the short-circuited or overloaded circuit from the supply. This provides protection to both electrical equipment and personnel.

The UPGF6-30421-18 is suitable for a variety of applications, including automotive, medical, industrial, and telecoms. The circuit breaker is also suitable for use in harsh environments, such as those exposed to high levels of vibration, extreme temperatures, and corrosive atmospheres. The circuit breaker is also suitable for use in circuits that require high levels of switching and/or electrical interference, such as those used in renewable energy systems or in medical imaging equipment.

The working principle of the UPGF6-30421-18 is relatively simple. When the current passing through the circuit exceeds the rated limit, the fuse-link is designed to break the circuit. This causes an interruption in the flow of current, which in turn, causes the circuit breaker to trip. The fuse-link then needs to be replaced in order for the circuit to resume normal operation.

In summary, the UPGF6-30421-18 is a current-limiting circuit breaker that is designed to protect circuits from overcurrents. The circuit breaker is suitable for a wide range of applications, is suitable for use in a variety of harsh environments, and has a relatively simple working principle.
