40.703 is a rapid rise load limiting circuit breaker system built by the ABB Group of Companies. It is sold in two versions: an adjustable current model and an adjustable voltage model. The system is designed to prevent damage to power system components such as motors, transformers, and other electrical equipment. It also helps to improve the safety of the power system by providing short-circuit protection. The circuit breaker system is a reliable and cost-effective solution for protecting against power system faults, and is widely used in the power industry.

The 40.703 circuit breaker system is a type of electronic device usually referred to as an over-voltage or over-current protection switch. It is designed to detect and prevent the rapid rise of voltage and current by momentarily interrupting the supply of electric power. When a rapid rise in current or voltage occurs, the switch opens and the power supply to the system is terminated. This helps to keep equipment and individuals safe from damage or injury caused by current or voltage overload.

The circuit breaker system is composed of an electromechanical assembly of capacitive, inductive or resistive elements. The assembly is connected in parallel on the main bus and is designed to open when an over-current or over-voltage situation is detected. When the device senses an over-current or over-voltage situation, it interrupts the power and initiates a shut-down sequence. It also has the capability to isolate the power supply from the main system if the over-current or over-voltage continues for a prolonged period of time.

The 40.703 is suitable for applications such as transmission systems, electric motor drives, and utility switching systems. It can be connected directly to the main power system or installed into an existing system. It is designed to provide current overload protection and to reduce the risk of damage to the power system caused by over-voltage conditions. It is also designed to protect personnel from electric shock caused by an over-voltage or over-current situation.

The 40.703 circuit breaker system has a broad working temperature range, allowing it to work in a wide variety of environments. It has a built-in fault indicator that is easy to read and it has adjustable trip settings that enable it to be tailored to the power system in which it is installed. It also has a highly efficient operating system that is capable of providing superior protection against current and voltage overloads. All these features make the 40.703 a reliable and cost-effective solution for power system protection.
