1D3UM

Circuit breakers are electrical devices used for protection against excessive current flow in an electrical circuit. They are commonly used in buildings and factories, in order to prevent electrical fires from happening. A 1D3UM is a type of circuit breaker that is used to protect electrical circuits from overcurrent and is characterized by its low voltage, current and fast response time. The 1D3UM is a three-pole circuit breaker suitable for curved and rolling motor-generator sets, motor starters, generator sets and all kinds of pressurized systems.

The working principle of a 1D3UM circuit breaker is based on the principle of thermal release. When the current passing through the circuit breaker exceeds the design limit set by the manufacturer, a bimetallic strip is heated, resulting in a release of pressure in the circuit. This pressure release causes an interruption of the power supply to the circuit, thus protecting it from further damage. The 1D3UM circuit breaker also has a self-resetting capability, allowing the circuit to reset itself once the current normalizes.

The 1D3UM circuit breaker is mainly used in residential, commercial and industrial installations where the current carrying capacity of a single circuit is relatively large. It can be used to protect valuable equipment from high fault currents, as well as to reduce the risk of electric shock or fire due to an overcurrent condition. It is also commonly used to provide overcurrent protection for electric motors, pumps and switchgear.

The 1D3UM circuit breaker is a reliable device for protecting electrical circuits from extreme currents, and it is durable enough to withstand the frequent overloads that these circuits may experience. It is compact and easy to install, and its self-resetting feature makes it an ideal choice for industrial applications. In addition, the 1D3UM circuit breaker has a long-ageing life, making it a cost-effective solution for protecting circuits from power surges.

In conclusion, the 1D3UM circuit breaker is a reliable and cost-effective device used to protect electrical circuits from potential damage caused by excessive current flow. Its fast response time, long-ageing life and self-resetting feature make it an ideal choice for many applications. It is easy to install, and its durability makes it a good option for protecting valuable equipment from power surges and overloads.
