Circuit breakers are an integral part of an electrical system, and they are responsible for protecting electrical circuits from dangerous levels of overload or short circuit conditions. The 1C40UM is one type of circuit breaker commonly used in industrial applications. This article will discuss the application fields and working principle of the 1C40UM.

The 1C40UM is a low-voltage circuit breaker that is designed for use in a variety of industrial applications. It is suitable for use in a wide range of voltages, from 110 to 600 Volts. It is also suitable for use in both single-phase and three-phase applications. The 1C40UM is very durable and reliable, and can be installed in a variety of locations, including in hazardous areas. It is also capable of breaking large currents, up to 400 Amps.

The 1C40UM has an adjustable trip unit that allows for the adjustment of the trip thresholds for the thermal overload protection and short circuit protection. This allows the user to customize the circuit breaker to suit their individual needs. The trip unit also features two poles, one for each phase, which allows the user to separate each phase and provide better circuit protection. The adjustable trip unit includes current ranges from 335 to 4000 Amps.

The working principle of the 1C40UM is quite simple; when an overload or short circuit condition is detected, the trip unit will send a signal to the breaker, which will then trip and open the circuit. This breaks the flow of current and prevents any further damage to the components of the electrical system. The 1C40UM also has an adjustable time delay feature; this allows the user to delay the opening of the circuit for a preset time, allowing for the short circuit or overload condition to dissipate before the circuit is opened.

The 1C40UM is a durable and reliable circuit breaker that can be used in a variety of industrial applications. It offers adjustable trip thresholds for thermal overload and short circuit protection, as well as adjustable time delay for short circuit and overload protection. It is also suitable for use in a wide range of voltages and current levels, from 110 to 600 Volts and up to 4000 Amps. The 1C40UM is a great choice for industrial applications.
