Circuit breakers are mechanical or electrical switching devices used to protect electrical circuits from overloads or short-circuits, thereby preventing damage to electrical components or serious injury to personnel. The 203-11-6788-03 circuit breaker is typically used in medium-voltage applications (690 volts and below) to protect equipment and personnel from hazards created by fault currents.

This circuit breaker has a single-pole and three-pole rated interrupting capacity of 200 kilocalories of maximum energy absorption and 15kA for medium-voltage voltage. It is available in a range of trip range options that can be adjusted to match the currents in the circuit being protected. The 203-11-6788-03 circuit breaker is also designed to meet National Electric Code requirements including UL 489 and NFPA 70.

This circuit breaker operates on the principle of an electromechanical switch, which is triggered when an overcurrent or short-circuit is detected. It includes a release mechanism that allows the circuit breaker to trip and transfer the load automatically to prevent the electrical circuit from becoming overloaded or short-circuited. When a fault current is detected, the mechanism inside the circuit breaker causes an electrical contact to open, allowing the circuit breaker to open the voltage supply and prevent the current from proceeding further into the circuit.

The 203-11-6788-03 circuit breaker is designed to provide reliable and durable protection for low, moderate and high voltage applications. It is suitable for use in residential, commercial, industrial and utility settings, and can be applied to multiple types of enclosures. It is also designed with advanced safety features, such as built-in overvoltage protection, thermal magnetic trip units, and trip curves which can be adjusted for specific applications. This device is capable of providing maximum circuit protection from both short circuits and overvoltages while maintaining high efficiency.

In addition to its improved safety and efficiency, the 203-11-6788-03 circuit breaker offers improved accessibility with its externally operable handle. The handle has a locking mechanism to secure the switch in the "off" position and prevent inadvertent operation. This circuit breaker also provides a delay feature for opening and closing, allowing the user to control the switch from a distance if necessary. This makes the circuit breaker ideal for remote operation, as well as easy integration into existing systems.

The 203-11-6788-03 circuit breaker is a reliable and efficient device for electrical circuit protection in medium-voltage applications. Its advanced protection mechanism, flexible trip range adjustment, operable handle and remote operation capabilities make it an excellent choice for a wide variety of applications.
